Minimum output resolution depends on MPWMSM and MCPSM prescaler settings.
Maximum resolution is obtained by setting CPSMPSL[3:0] =0x2 and MPWMSCR_CP[7:0] =0xFF.
Excluding the case where the output is always “0”.
With MPWMSM enabled before enabling the MCPSM. Please also see NOTE 1 on the MCPSM timing
information.
The exact timing from MPWMSM enable to the pin being set depends on the timing of the register write and the
MCPSM VS_PCLK.
When MCPSMSCR_PSL = 0x0000, this gives a prescale value of 16 and it is 16 which should be used in these
calculations. When MCPSMSCR_PSL = 0x0001, the CPSM is inactive.
The interrupt is set before the output pin is reset (Signifying the start of a new period).
