The CCP module does not assert control of the CCP1 pin in this mode (see the CCP1CON register). The Special Event Trigger output of the CCP occurs immediately upon a match between the TMR1H, TMR1L register pair and the CCPR1H, CCPR1L register pair.
The TMR1H, TMR1L register pair is not reset until the next rising edge of the Timer1 clock. This allows the CCPR1H, CCPR1L register pair to effectively provide a 16-bit programmable period register for Timer1 if microcontroller atmega1281 program copying.
The PWM mode generates a Pulse-Width Modulated signal on the CCP1 pin. The duty cycle, period and resolution are determined by the following registers:
In Pulse-Width Modulation (PWM) mode, the CCP module produces up to a 10-bit resolution PWM output on the CCP1 pin. Since the CCP1 pin is multiplexed with the PORT data latch, the TRIS for that pin must be cleared to enable the CCP1 pin output driver.
For a step-by-step procedure on how to set up the CCP module for PWM operation, see Section 11.3.7 “Setup for PWM Operation” after IC ATmega2561 program copying.
The PWM output (Figure 11-4) has a time base (period) and a time that the output stays high (duty cycle). The PWM period is specified by the PR2 register of Timer2. The PWM period can be calculated using the formula of Equation.
When TMR2 is equal to PR2, the following three events occur on the next increment cycle:
- TMR2 is cleared
- The CCP1 pin is set. (Exception: If the PWM duty cycle = 0%, the pin will not be set.)
- The PWM duty cycle is latched from CCPR1L into CCPR1H.
The PWM duty cycle is specified by writing a 10-bit value to multiple registers: CCPR1L register and DC1B<1:0> bits of the CCP1CON register. The CCPR1L contains the eight MSbs and the DC1B<1:0> bits of the CCP1CON register contain the two LSbs if microcontroller attiny48 hex copying.
CCPR1L and DC1B<1:0> bits of the CCP1CON register can be written to at any time. The duty cycle value is not latched into CCPR1H until after the period completes (i.e., a match between PR2 and TMR2.
The resolution determines the number of available duty cycles for a given period. For example, a 10-bit resolution will result in 1024 discrete duty cycles, whereas an 8-bit resolution will result in 256 discrete duty cycles.
The maximum PWM resolution is 10 bits when PR2 is The resolution is a function of the PR2 register value as shown by Equation 11-4 registers occurs). While using the PWM, the CCPR1H register is read-only.
