Note: 1. STM [1:0]=01 and active edge set by the STIO [1:0] bits
2. A STM Capture input pin active edge transfers the counter value to CCRA
3. STCCLR bit not used
4. No output function – STOC and STPOL bits are not used
5. CCRP determines the counter value and the counter has a maximum count value when CCRP is equal to
zero
