Counter Operation
buffer register and cleared on an UPDATE condition. This is shown for a compare register in
Figure 14-4 on page
Figure 14-4. Period and compare double buffering
When the CC channels are used for a capture operation, a similar double buffering mechanism
is used, but in this case the buffer valid flag is set on the capture event, as shown in
For capture, the buffer register and the corresponding CCx register act like a FIFO. When the
CC register is empty or read, any content in the buffer register is passed to the CC register. The
buffer valid flag is passed to set the CCx interrupt flag (IF) and generate the optional interrupt.
Figure 14-5. Capture double buffering.
Both the CCx and CCxBUF registers are available as an I/O register. This allows initialization
and bypassing of the buffer register and the double buffering function.
Depending on the mode of operation, the counter is cleared, reloaded, incremented, or decre-
mented at each timer/counter clock input.
