General Purpose Timer Modules (GPTA and GPTB)
The processor has two 4-channel general purpose timer modules (GPTA and GPTB). Each consists of a
16-bit counter driven by a 7-stage programmable prescaler.
A timer overflow function allows software to extend the timing capability of the system beyond the 16-bit
range of the counter. Each of the four timer channels can be configured for input capture, which can
capture the time of a selected transition edge, or for output compare, which can generate output waveforms
and timer software delays. These functions allow simultaneous input waveform measurements and output
waveform generation.
Additionally, one of the channels, channel 3, can be configured as a 16-bit pulse accumulator that can
operate as a simple event counter or as a gated time accumulator. The pulse accumulator uses the GPT
channel 3 input/output pin in either event mode or gated time accumulation mode.
