Pin input status bit — The PIN bit reflects the state present on the MPWMSM signal. The
software can thus monitor the pin state.
The PIN bit is a read-only bit. Writing to the PIN bit has no effect.
Data direction register — The DDR bit indicates the direction for the signal when the PWM
function is not used (disable mode).
0 signal is in input.
1 signal is in output.
The DDR bit is cleared by reset.

direction register (DDR) bit.
Freeze enable bit — This active high read/write control bit enables the MPWMSM to recognize
the freeze signal on the MIOB.
0 MPWMSM not frozen even if the MIOB freeze line is active.
1 MPWMSM frozen if the MIOB freeze line is active.
The FREN is cleared by reset.
Transparent mode — The TRSP bit indicates that the MPWMSM is in transparent mode. In
transparent mode, when the software writes to either the MPWMPERR or MPWMPULR1 register
the value written is immediately transferred to the counter or register MPWMPULR2 respectively.
0 Double-buffered mode.
1 Transparent mode.
The TRSP bit is cleared by reset.
Output polarity control bit — The POL bit works in conjunction with the EN bit and controls
whether the MPWMSM drives the signal with the direct or the inverted value of the output flip-flop.

direction register (DDR) bit.
Enable PWM signal generation — The EN bit defines whether the MPWMSM generates a PWM
signal or is used as an I/O channel:
0 PWM generation disabled (signal can be used as I/O).
1 PWM generation enabled (the signal is in output mode).
Each time the submodule is enabled, the value of CP is loaded into the prescaler.
The EN bit is cleared by reset.
Reserved
Clock prescaler — This 8-bit read/write data register stores the modulus value for loading into
the built-in 8-bit clock prescaler. The value loaded defines the divide ratio for the signal that clocks
the MPWMSM. The new value is loaded into the prescaler counter on the prescaler counter
overflow, or upon the EN bit of the MPWMSCR being set.
