Relationships:

• Period = 4 * TOSC * (PR2 + 1) * (TMR2 Prescale Value)

• Pulse Width = TOSC * (CCPR1L<7:0>:CCP1CON<5:4>) * (TMR2 Prescale Value)

• Delay = 4 * TOSC * (PWM1CON<6:0>)

Note 1: Dead-band delay is programmed using the PWM1CON register (Section 11.6.6 “Programmable Dead-Band Delay

Mode”).
