Capture/Compare Control Registers
The Compare State Register CMPSTAT contains status bits monitoring the current
capture and compare state and control bits defining the active/passive state of the
compare channels.

1
Bits CC6xST monitor the state of the capture/

compare channels. Bits CC6xST (x=0, 1, 2) are
6
related to T12, bit CC63ST is related to T13.
0 In compare mode, the timer count is less than
the compare value. In capture mode, the
selected edge has not yet been detected since
the bit has been reset by SW the last time.
1 In compare mode, the counter value is greater
than or equal to the compare value. In capture
mode, the selected edge has been detected.
