MITSUBISHI MICROCOMPUTERS 3802 Group SINGLE-CHIP 8-BIT CMOS MICROCOMPUTER I/O Ports Direction registers The 3802 group has 56 programmable I/O pins arranged in seven I/O ports (ports P0 to P6). The I/O ports have direction registers which determine the input/output direction of each individual pin. Each bit in a direction register corresponds to one pin, each pin can be set to be input port or output port. When “0” is written to the bit corresponding to a pin, that pin becomes an input pin.

MITSUBISHI MICROCOMPUTERS 3802 Group SINGLE-CHIP 8-BIT CMOS MICROCOMPUTER INTERRUPTS Interrupt operation Interrupts occur by sixteen sources: seven external, eight internal, and one software. When an interrupt is received, the contents of the program counter and processor status register are automatically stored into the stack. The interrupt disable flag is set to inhibit other interrupts from interfering.

MITSUBISHI MICROCOMPUTERS 3802 Group SINGLE-CHIP 8-BIT CMOS MICROCOMPUTER Timers Timer 1 and Timer 2 The 3802 group has four timers: timer X, timer Y, timer 1, and timer 2. All timers are count down. When the timer reaches “0016 ”, an underflow occurs at the next count pulse and the corresponding timer latch is reloaded into the timer and the count is continued. When a timer underflows, the interrupt request bit corresponding to that timer is set to “1”.

MITSUBISHI MICROCOMPUTERS 3802 Group SINGLE-CHIP 8-BIT CMOS MICROCOMPUTER Serial I/O1 Clock synchronous serial I/O mode Serial I/O1 can be used as either clock synchronous or asynchronous (UART) serial I/O. A dedicated timer is also provided for baud rate generation. Clock synchronous serial I/O1 mode can be selected by setting the mode selection bit of the serial I/O1 control register to “1”. For clock synchronous serial I/O1, the transmitter and the receiver must use the same clock.
MITSUBISHI MICROCOMPUTERS 3802 Group SINGLE-CHIP 8-BIT CMOS MICROCOMPUTER Asynchronous serial I/O (UART) mode two buffers have the same address in memory. Since the shift register cannot be written to or read from directly, transmit data is written to the transmit buffer, and receive data is read from the receive buffer. The transmit buffer can also hold the next data to be transmitted, and the receive buffer can hold a character while the next character is being received.

MITSUBISHI MICROCOMPUTERS 3802 Group SINGLE-CHIP 8-BIT CMOS MICROCOMPUTER Serial I/O2 b7 b0 The serial I/O2 function can be used only for clock synchronous serial I/O. For clock synchronous serial I/O the transmitter and the receiver must use the same clock. If the internal clock is used, transfer is started by a write signal to the serial I/O2 register.

MITSUBISHI MICROCOMPUTERS 3802 Group SINGLE-CHIP 8-BIT CMOS MICROCOMPUTER PULSE WIDTH MODULATION (PWM) PWM Operation The 3802 group has a PWM function with an 8-bit resolution, based on a signal that is the clock input X IN or that clock input divided by 2. When bit 0 (PWM enable bit) of the PWM control register is set to “1”, operation starts by initializing the PWM output circuit, and pulses are output starting at an “H”.

MITSUBISHI MICROCOMPUTERS 3802 Group SINGLE-CHIP 8-BIT CMOS MICROCOMPUTER A-D Converter [Comparator and Control circuit] The functional blocks of the A-D converter are described below. The comparator and control circuit compares an analog input voltage with the comparison voltage, then stores the result in the A-D conversion register. When an A-D conversion is complete, the control circuit sets the AD conversion completion bit and the AD interrupt request bit to “1”.
MITSUBISHI MICROCOMPUTERS 3802 Group SINGLE-CHIP 8-BIT CMOS MICROCOMPUTER D-A Converter The 3802 group has two internal D-A converters (DA1 and DA2) with 8-bit resolutions. The D-A converter is performed by setting the value in the D-A conversion register. The result of D-A converter is output from the DA 1 or DA2 pin by setting the DA output enable bit to “1”. When using the D-A converter, the corresponding port direction register bit (P30 /DA1 or P31/DA 2 ) should be set to “0” (input status).
MITSUBISHI MICROCOMPUTERS 3802 Group SINGLE-CHIP 8-BIT CMOS MICROCOMPUTER Reset Circuit To reset the microcomputer, the RESET pin should be held at an “L” level for 2 µs or more. Then the RESET pin is returned to an “H” level (the power source voltage should be between 4.0 V and 5.5 V), reset is released. Internal operation begin until after 8 to 13 X IN clock cycles are completed.

MITSUBISHI MICROCOMPUTERS 3802 Group SINGLE-CHIP 8-BIT CMOS MICROCOMPUTER Clock Generating Circuit An oscillation circuit can be formed by connecting a resonator between XIN and XOUT . To supply a clock signal externally, input it to the XIN pin and make the XOUT pin open. When the STP status is released, prescaler 12 and timer 1 will start counting and reset will not be released until timer 1 underflows, so set the timer 1 interrupt enable bit to “0” before the STP instruction is executed.
MITSUBISHI MICROCOMPUTERS 3802 Group SINGLE-CHIP 8-BIT CMOS MICROCOMPUTER Processor Modes Single-chip mode, memory expansion mode, and microprocessor mode can be selected by changing the contents of the processor mode bits CM 0 and CM 1 (bits 0 and 1 of address 003B 16). In memory expansion mode and microprocessor mode, memory can be expanded externally through ports P0 to P3. In these modes, ports P0 to P3 lose their I/O port functions and become bus pins. Table 2.
MITSUBISHI MICROCOMPUTERS 3802 Group SINGLE-CHIP 8-BIT CMOS MICROCOMPUTER Bus control with memory expansion The 3802 group has a built-in ONW function to facilitate access to external memory and I/O devices in memory expansion mode or microprocessor mode. If an “L” level signal is input to the ONW pin when the CPU is in a read or write state, the corresponding read or write cycle is extended by one cycle of φ. During this extended period, the RD or WR signal remains at “L”.
MITSUBISHI MICROCOMPUTERS 3802 Group SINGLE-CHIP 8-BIT CMOS MICROCOMPUTER NOTES ON PROGRAMMING Processor Status Register The contents of the processor status register (PS) after a reset are undefined, except for the interrupt disable flag (I) which is “1”. After a reset, initialize flags which affect program execution. In particular, it is essential to initialize the index X mode (T) and the decimal mode (D) flags because of their effect on calculations.
