PWM OUTPUT RELATIONSHIPS (ACTIVE-HIGH STATE)
FIGURE 16-3:
PWM OUTPUT RELATIONSHIPS (ACTIVE-LOW STATE)
Relationships:
Period = 4 * TOSC * (PR2 + 1) * (TMR2 Prescale Value)
Duty Cycle = 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 (see Section 16.4.4 “Programmable Dead-Band Delay”).
