NOTES:
MPWMSM interrupt flag
1. Minimum output resolution depends on MMCSM and MCPSM prescaler settings.
2. Maximum resolution is obtained by setting CPSMPSL[3:0] = 0x2 and MMCSMSCR_CP[7:0] = 0xFF.
3. When MCPSMSCR_PSL = 0x0000, this gives a prescale value of 16 and it is 16 which should be used in these
4. The exact timing from MMCSM enable to the pin being set depends on the timing of the MMCSMSCR register
