MPWMSM Enable to output set (MAX)
Interrupt Flag to output pin reset (period
start)
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).
