Relationships:
• Period = 4 * TOSC * (PR2 + 1) * (TMR2 Prescale Value)
• Pulse Width = TOSC * (CCPR1L<7:0>:CCP1CON<5:4>) * (TMR2 Prescale Value)
• Delay = 4 * TOSC * (ECCP1DEL<6:0>)
Note 1: Dead-band delay is programmed using the ECCP1DEL register (Section 20.4.6 “Programmable Dead-Band
Delay Mode”).
