3.5
The CAPCOM unit supports generation and control of timing sequences on up to
16 channels with a maximum resolution of 1 system clock cycle (8 cycles in staggered
mode). The CAPCOM 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 relative 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 several prescaled values of the internal
system clock, or may be derived from an overflow/underflow of timer T6 in module GPT2.
This provides a wide range of variation for the timer period and resolution and allows
precise adjustments to the application specific requirements. In addition, an external
count input for CAPCOM timer T7 allows event scheduling for the capture/compare
registers relative to external events.
The capture/compare register array contains 16 dual purpose capture/compare
registers, each of which may be individually allocated to either CAPCOM timer (T7 or T8,
respectively), and programmed for capture or compare function.
10 registers of the CAPCOM2 module have each one port pin associated with it which
serves as an input pin for triggering the capture function, or as an output pin to indicate
the occurrence of a compare event.
