Pulse Width Modulator (PWM)
Register 46: PWM0 Dead-Band Falling-Edge-Delay (PWM0DBFALL), offset
0x070
Register 47: PWM1 Dead-Band Falling-Edge-Delay (PWM1DBFALL), offset
0x0B0
Register 48: PWM2 Dead-Band Falling-Edge-Delay (PWM2DBFALL), offset
0x0F0
The PWM0DBFALL register contains the number of clock ticks to delay the falling edge of the
PWM0A signal when generating the PWM1 signal. If the dead-band generator is disabled, this register
is ignored. If the value of this register is larger than the width of a Low pulse on the input PWM
signal, the falling-edge delay consumes the entire Low time of the signal, resulting in no Low time
on the output. Care must be taken to ensure that the input Low time always exceeds the falling-edge
delay. In a similar manner, PWM3 is generated from PWM1A with its falling edge delayed and PWM5
is produced from PWM2A with its falling edge delayed.

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.
Dead-Band Fall Delay
The number of clock ticks to delay the falling edge.
