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.
SD16_A
The SD16_A module integrates in MSP430x47x3 three and in MSP430x47x4 four 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 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 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.
