Relationships:
• Period = 4 * T
OSC * (PR2 + 1) * (TMR2 Prescale Value)
• Pulse Width = T
OSC * (CCPRxL<7:0>:CCPxCON<5:4>) * (TMR2 Prescale Value)
• Delay = 4 * T
OSC * (ECCPxDEL<6:0>)
Note 1: Dead-band delay is programmed using the ECCP1DEL register (Section 18.5.6 “Programmable Dead-Band
Delay Mode”).
