PWM0 Signal
PWM0 Signal
PWM Nonoverlapping Output Pair Delays
If you enable the OR function on all PWM outputs and PADR0 is set to 1, then the PWM0
output on PA0 is forced High. Similarly, if you select the AND function on all PWM
outputs and PADR0 is set to a 0, then the PWM0 output on PA0 is forced Low.
A delay is added between the falling edge of the PWM (PWM) outputs and the rising edge
of the PWM (PWM) outputs. This delay is set to assure that even with load and output
drive variations there will be no overlap between the falling edge of a PWM (PWM) out-
put and the rising edge of its paired output. The selected delay is global to all four PWM
pairs. The delay duration is software-selectable using the 4-bit field
TMR3_PWM_CTL2[PWM_DLY]. The duration is programmable in units of the system
clock (SCLK), from 0 SCLK periods to 15 SCLK periods. The
TMR3_PWM_CTL2[PWM_DLY] bits are mapped directly to a counter, such that a
