6.9.11 Timer_B3
Timer_B3 is a 16-bit timer/counter with three capture/compare registers. Timer_B3 can support multiple
capture/compares, PWM outputs, and interval timing. Timer_B3 also has extensive interrupt capabilities.
Interrupts may be generated from the counter on overflow conditions and from each of the
capture/compare registers.

6.9.12 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.
6.9.13 ADC12
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.
6.9.14 DAC12
The DAC12 module is a 12-bit, R-ladder, voltage output DAC. The DAC12 may be used in 8- or 12-bit
mode, and may be used in conjunction with the DMA controller. When multiple DAC12 modules are
present, they may be grouped together for synchronous operation.
