The Capture/Compare Unit CAPCOM2
The general purpose CAPCOM2 unit supports generation and control of timing
sequences on up to 8 channels with a maximum resolution of 16 TCL. The CAPCOM
units are typically used to handle high speed I/O tasks such as pulse and waveform
generation, pulse width modulation (PMW), 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.
Each dual purpose capture/compare register, which may be individually allocated to
either CAPCOM timer and programmed for capture or compare function, has 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.
When a capture/compare register has been selected for capture mode, the current
contents of the allocated timer will be latched (‘capture’d) into the capture/compare
register in response to an external event at the port pin which is associated with this
register. In addition, a specific interrupt request for this capture/compare register is
generated. Either a positive, a negative, or both a positive and a negative external signal
transition at the pin can be selected as the triggering event. The contents of all registers
which have been selected for one of the five compare modes are continuously compared
with the contents of the allocated timers. When a match occurs between the timer value
and the value in a capture/compare register, specific actions will be taken based on the
selected compare mode.
