6.2 Capture/Compare Unit
MC68331TS/D
The capture/compare unit features three input capture channels, four output compare channels, and
one input capture/output compare channel (function selected by control register). These channels share
a 16-bit free-running counter (TCNT), which derives its clock from seven stages of a 9-stage prescaler
or from external clock input PCLK. This section, which is similar to the timer found on the MC68HC11F1,
also contains one pulse accumulator channel. The pulse accumulator logic includes its own 8-bit
counter and can operate in either event counting mode or gated time accumulation mode. Refer to the
following block diagrams of the GPT timer and prescaler.
Y = M111, where M is the logic state of the modmap (MM) bit in SIMCR.
