LCD_A drive with regulated charge pump
The LCD_A driver generates the segment and common signals required to drive an LCD display. The LCD_A
controller has dedicated data memory to hold segment drive information. Common and segment signals are
generated as defined by the mode. Static, 2-MUX, 3-MUX, and 4-MUX LCDs are supported by this peripheral.
The module can provide a LCD voltage independent of the supply voltage with its integrated charge pump.
Furthermore it is possible to control the level of the LCD voltage and, thus, contrast by software.
watchdog timer (WDT+)
The primary function of the WDT+ module is to perform a controlled system restart after a software problem
occurs. If the selected time interval expires, a system reset is generated. If the watchdog function is not needed
in an application, the module can be configured as an interval timer and can generate interrupts at selected time
intervals.
universal serial communication interface (USCI)
The USCI modules are used for serial data communication. The USCI module supports synchronous
communication protocols like SPI (3 or 4 pin), I2C and asynchronous communication protocols like UART,
enhanced UART with automatic baudrate detection, and IrDA.
The USCI_A0 module provides support for SPI (3 or 4 pin), UART, enhanced UART and IrDA.
The USCI_B0 module provides support for SPI (3 or 4 pin) and I2C.
USART1
The hardware universal synchronous/asynchronous receive transmit (USART) peripheral module is used for
serial data communication. The USART supports synchronous SPI (3 or 4 pin) and asynchronous UART
communication protocols, using double-buffered transmit and receive channels.
hardware multiplier
The multiplication operation is supported by a dedicated peripheral module. The module performs 16 16,
16 8, 8 16, and 8 8 bit operations. The module is capable of supporting signed and unsigned multiplication,
as well as signed and unsigned multiply and accumulate operations. The result of an operation can be accessed
immediately after the operands have been loaded into the peripheral registers. No additional clock cycles are
required.
