The CAPCOM2 unit supports generation and control of timing sequences on up to
16 channels with a maximum resolution of one system clock cycle (eight cycles in
staggered mode). The CAPCOM2 unit is typically used to handle high-speed I/O tasks
such as pulse and waveform generation, pulse width modulation (PWM), digital to
analog (D/A) conversion, software timing, or time recording with respect to external
events.
Two 16-bit timers (T7/T8) with reload registers provide two independent time bases for
the capture/compare register array.
The input clock for the timers is programmable to a number of prescaled values of the
internal system clock. It may also be derived from an overflow/underflow of timer T6 in
module GPT2. This provides a wide range for the timer period and resolution while
allowing precise adjustments for application-specific requirements. An external count
input for CAPCOM2 timer T7 allows event scheduling for the capture/compare registers
with respect to external events.
The capture/compare register array contains 16 dual purpose capture/compare
registers. Each may be individually allocated to either CAPCOM2 timer T7 or T8 and
programmed for a capture or compare function.
Each register of the CAPCOM2 module has one port pin associated with it.A port pin is
associated with 8 registers of the CAPCOM2 module. This serves as an input pin to
trigger the capture function or as an output pin to indicate the occurrence of a compare
event.
