LCD drive
The LCD driver generates the segment and common signals required to drive an LCD display. The LCD
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.
OA
The MSP430FG43x has three configurable low-current general-purpose operational amplifiers. Each OA input
and output terminal is software-selectable and offers a flexible choice of connections for various applications.
The OA op amps primarily support front-end analog signal conditioning prior to analog-to-digital conversion.
watchdog timer
The primary function of the watchdog timer (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.
USART0
The MSP430FG43x has one hardware universal synchronous/asynchronous receive transmit (USART)
peripheral module that 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.
timer_A3
Timer_A3 is a 16-bit timer/counter with three capture/compare registers. Timer_A3 can support multiple
capture/compares, PWM outputs, and interval timing. Timer_A3 also has extensive interrupt capabilities.
Interrupts may be generated from the counter on overflow conditions and from each of the capture/compare
registers.
