MITSUBISHI MICROCOMPUTERS 3886 Group SINGLE-CHIP 8-BIT CMOS MICROCOMPUTER I/O PORTS 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, and 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. When “1” is written to that bit, that pin becomes an output pin.

MITSUBISHI MICROCOMPUTERS 3886 Group SINGLE-CHIP 8-BIT CMOS MICROCOMPUTER Functional Outline (serial I/O mode) Data is transferred in units of eight bits. In the first transfer, the user inputs the command code. This is followed by address input and data input/output according to the contents of the command. Table 26 shows the software commands used in the serial I/O mode. The following explains each software command.
MITSUBISHI MICROCOMPUTERS 3886 Group SINGLE-CHIP 8-BIT CMOS MICROCOMPUTER ● Program command Input command code 4016 in the first transfer. Proceed and input the low-order 8 bits and the high-order 8 bits of the address and then program data. Programming is initiated at the last rising edge of the serial clock during program data transfer. The BUSY pin is driven high during program operation. Programming is completed within 10 µs as measured by the internal timer, and the BUSY pin is pulled low.
MITSUBISHI MICROCOMPUTERS 3886 Group SINGLE-CHIP 8-BIT CMOS MICROCOMPUTER ● Erase command Input command code 2016 in the first transfer and command code 20 16 again in the second transfer.
