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 400 ns (at 20 MHz system clock). 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
occurence 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.
