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.

SD16_A
The SD16_A module supports 16-bit analog-to-digital conversions. The module implements a 16-bit
sigma-delta core and reference generator. In addition to external analog inputs, an internal V
CC
sense and
temperature sensor are also available.
DAC12
The DAC12 module is a 12-bit, R-ladder, voltage output DAC. The DAC12 may be used in 8- or 12-bit mode.
