Bit 6
—
When Timer1 is configured for asynchronous operation, the TMR1 registers will continue to
increment for each timer clock (or prescale multiple of clocks). When the TMR1 register over-
flows, the TMR1IF bit will get set, and if enabled generate an interrupt that will wake the
processor from sleep mode.
The Timer1 oscillator will add a delta current, due to the operation of this circuitry. That is, the
power-down current will no longer only be the leakage current of the device, but also the active
current of the Timer1 oscillator and other Timer1 circuitry.
If a CCP module is configured in compare mode to generate a “special event trigger”
(CCP1M3:CCP1M0 = 1011), this signal resets Timer1.
Timer1 must be configured for either timer or synchronized counter mode to take advantage of
the special event trigger feature. If Timer1 is running in asynchronous counter mode, this reset
operation may not work, and should not be used.
In the event that a write to Timer1 coincides with a special event trigger from the CCP module,
the write will take precedence.
In this mode of operation, the CCPRxH:CCPRxL register pair effectively becomes the period
register for Timer1.
TMR1H and TMR1L registers are not reset on a POR or any other reset, only by the CCP special
event triggers.
T1CON register is reset to 00h on a Power-on Reset or a Brown-out Reset. In any other reset,
the register is unaffected.
The prescaler counter is cleared on writes to the TMR1H or TMR1L registers.
