comparator_A
The primary function of the comparator_A module is to support precision slope A/D conversions, battery-voltage
supervision, and monitoring of external analog signals.
SD16_A
The SD16_A module integrates three (in MSP430F47x3) or four (in MSP430F47x4) independent 16-bit
sigma−delta A/D converters. Each channel is designed with a fully differential analog input pair and
programmable-gain amplifier input stage. In addition to external analog inputs, an internal V
CC
sense and
temperature sensor are also available.
Basic Timer1
The Basic Timer1 has two independent 8-bit timers that can be cascaded to form a 16-bit timer/counter. Both
timers can be read and written by software. Basic Timer1 can be used to generate periodic interrupts and a clock
for the LCD module.
LCD driver 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 via an integrated charge pump.
Furthermore, it is possible to control the level of the LCD voltage and, thus, contrast in software.
