C504
Capture/Compare Unit
The Capture/Compare Unit (CCU) of the C504 consists of a 16-bit 3-channel capture/
compare unit (CAPCOM) and a 10-bit 1-channel compare unit (COMP). In compare
mode, the CAPCOM unit provides two output signals per channel, which can have
inverted signal polarity and non-overlapping pulse transitions. The COMP unit can
generate a single PWM output signal and is further used to modulate the CAPCOM
output signals. In capture mode, the value of the Compare Timer 1 is stored in the
capture registers if a signal transition occurs at the pins CCx. Figure 11 shows the block
diagram of the CCU.
