17.10.3.7 MPWMSM Status and Control Register (SCR)
One register is used to initialize the MPWMSM and monitor its operation. Control bits are included to
allow the software to enable the PWM generator, establish the output signal polarity, select the counter
clock rate and set the glitch-free mode. A status bit is included to allow the software to read the state of
the output signal.
17.10.3.8 MPWMSM Interrupt
A valid MPWMSM interrupt is recognized when a pulse occurs on the flag line to set the flag bit and the
interrupt enable bit is set for the corresponding level in the MIRSM (Refer to
Section 17.12.1, “MIOS14 Interrupt Structure
and
Section 17.12.2, “MIOS14 Interrupt
for details about interrupts). A set flag pulse is generated at the start of
every period.
