comparator_A

The primary function of the comparator_A module is to support precision slope analog−to−digital conversions,

battery−voltage supervision, and monitoring of external analog signals.

ADC12 (Not implemented in the MSP430x43x1)

The ADC12 module supports fast, 12-bit analog-to-digital conversions. The module implements a 12-bit SAR

core, sample select control, reference generator and a 16 word conversion-and-control buffer. The

conversion-and-control buffer allows up to 16 independent ADC samples to be converted and stored without

any CPU intervention.

Basic Timer1

The Basic Timer1 has two independent 8-bit timers which can be cascaded to form a 16-bit timer/counter. Both

timers can be read and written by software. The Basic Timer1 can be used to generate periodic interrupts and

clock for the LCD module.

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.
