Changing Between Capture Modes
CCP Prescaler
Sleep Operation
Effects of a Reset
When the Capture mode is changed, a capture interrupt may be generated. The user should
keep the CCPxIE bit clear to disable these interrupts and should clear the CCPxIF flag bit
following any such change in operating mode.
There are four prescaler settings, specified by bits CCPxM3:CCPxM0. Whenever the CCP mod-
ule is turned off, or the CCP module is not in capture mode, the prescaler counter is cleared. This
means that any reset will clear the prescaler counter.
Switching from one capture prescale setting to another may generate an interrupt. Also, the pres-
caler counter will not be cleared, therefore the first capture may be from a nonzero prescaler.
Example 14-1
This example also clears the prescaler counter and will not generate the interrupt.
Example 14-1:
To clear the Capture prescaler count, the CCP module must be configured into any non-capture
CCP mode (Compare, PWM, or CCP off modes).
When the device is placed in sleep, Timer1 will not increment (since it is in synchronous mode),
but the prescaler will continue to count events (not synchronized). When a specified capture
event occurs, the CCPxIF bit will be set, but the capture register will not be updated. If the CCP
interrupt is enabled, the device will wake-up from sleep. The value in the 16-bit TMR1 register is
not transferred to the 16-bit capture register, but since the timer was not incrementing, this value
should not have any meaning. Effectively, this allows the CCP pin to be used as another external
interrupt.
The CCP module is off, and the value in the capture prescaler is forced to 0.
