Relationships:
• Period = 4 * TOSC * (PRx + 1) * (TMRx Prescale Value)
• Pulse Width = TOSC * (CCPRxL<7:0>:CCPxCON<5:4>) * (TMRx Prescale Value)
• Delay = 4 * TOSC * (PWMxCON<6:0>)
Note 1: Dead-band delay is programmed using the PWMxCON register (Section 14.4.5 “Programmable Dead-Band Delay
Mode”).
