Toggle Output select
Note: 1. With PTnCCLR=1, a Comparator A match will clear the counter
2. The PTMn output pin is controlled only by the PTMnAF flag
3. The output pin is reset to its initial state by a PTnON bit rising edge
4. A PTMnPF flag is not generated when PTnCCLR =1
5. The 10-bit PTM maximum counter value is 0x3FF while the 16-bit PTM maximum counter value is
0xFFFF.
6. n=0, 1, 4, 5, 6 or 7 for 10-bit PTM while n=2 or 3 for 16-bit PTM
