Pulse Width Modulator (PWM)
Register 67: PWM0 Minimum Fault Period (PWM0MINFLTPER), offset 0x07C
Register 68: PWM1 Minimum Fault Period (PWM1MINFLTPER), offset 0x0BC
Register 69: PWM2 Minimum Fault Period (PWM2MINFLTPER), offset 0x0FC
Register 70: PWM3 Minimum Fault Period (PWM3MINFLTPER), offset 0x13C
If the MINFLTPER bit in the PWMnCTL register is set, this register specifies the 16-bit time-extension
value to be used in extending the fault condition. The value is loaded into a 16-bit down counter,
and the counter value is used to extend the fault condition. The fault condition is released in the
clock immediately after the counter value reaches 0. The fault condition is asynchronous to the
PWM clock; and the delay value is the product of the PWM clock period and the (MFP field value
+ 1) or (MFP field value + 2) depending on when the fault condition asserts with respect to the PWM
clock. The counter decrements at the PWM clock rate, without pause or condition.

Description
Software should not rely on the value of a reserved bit. To provide
compatibility with future products, the value of a reserved bit should be
preserved across a read-modify-write operation.
Minimum Fault Period
The number of PWM clocks by which a fault condition is extended when
the delay is enabled by PWMnCTL MINFLTPER.
