As the TPnA and TPnB_0, TPnB_1, TPnB_2 pins are pin shared with other functions, care must be

taken if the TM is in the Capture Input Mode. This is because if the pin is setup as an output, then any

transitions on this pin may cause an input capture operation to be executed. The TnCCLR, TnAOC,

TnBOC, TnAPOL and TnBPOL bits are not used in this mode.

Note:

1. TnBM [1:0] = 01 and active edge set by the TnBIO [1:0] bits

2. The TM Capture input pin active edge transfers the counter value to CCRB

3. TnCCLR bit not used

4. No output function -- TnBOC and TnBPOL bits not used

5. CCRP determines the counter value and the counter has a maximum count value when CCRP

is equal to zero.
