Relationships:

• Period = 4 * T

OSC

* (PR2 + 1) * (TMR2 Prescale Value)

• Duty Cycle = T

OSC

* (CCPR1L<7:0>:CCP1CON<5:4>) * (TMR2 Prescale Value)

• Delay = 4 * T

OSC

* (ECCP1DEL<6:0>)

Note

Dead-band delay is programmed using the ECCP1DEL register (Section 18.4.6 “Programmable
Dead-Band Delay”).
