7.6
Timer1 gate source is software configurable to be the
T1G pin (or the alternate T1G pin) or the output of the
Comparator. This allows the device to directly time
external events using T1G or analog events using the
Comparator. See the CMCON1 Register (Register 9-2)
for selecting the Timer1 gate source. This feature can
simplify the software for a Delta-Sigma A/D converter
and many other applications. For more information on
Delta-Sigma A/D converters, see the Microchip web site
(www.microchip.com).
Timer1 gate can be inverted using the T1GINV bit of
the T1CON register, whether it originates from the T1G
pin or the Comparator output. This configures Timer1
to measure either the active-high or active-low time
between events.
7.7
The Timer1 register pair (TMR1H:TMR1L) increments
to FFFFh and rolls over to 0000h. When Timer1 rolls
over, the Timer1 interrupt flag bit of the PIR1 register is
set. To enable the interrupt on rollover, you must set
these bits:
• Timer1 interrupt enable bit of the PIE1 register
• PEIE bit of the INTCON register
• GIE bit of the INTCON register
The interrupt is cleared by clearing the TMR1IF bit in
the Interrupt Service Routine.
7.8
Timer1 can only operate during Sleep when setup in
Asynchronous Counter mode. In this mode, an external
crystal or clock source can be used to increment the
counter. To set up the timer to wake the device:
• TMR1ON bit of the T1CON register must be set
• TMR1IE bit of the PIE1 register must be set
• PEIE bit of the INTCON register must be set
The device will wake-up on an overflow and execute
the next instruction. If the GIE bit of the INTCON
register is set, the device will call the Interrupt Service
Routine (0004h).

Timer1 Operation During Sleep
TMR1GE bit of the T1CON register must
be set to use either T1G or COUT as the
Timer1 gate source. See Register 9-2 for
more information on selecting the Timer1
gate source.
The TMR1H:TTMR1L register pair and the
TMR1IF bit should be cleared before
enabling interrupts.
7.9
The ECCP module uses the TMR1H:TMR1L register
pair as the time base when operating in Capture or
Compare mode.
In Capture mode, the value in the TMR1H:TMR1L
register pair is copied into the CCPR1H:CCPR1L
register pair on a configured event.
In Compare mode, an event is triggered when the value
CCPR1H:CCPR1L register pair matches the value in
the TMR1H:TMR1L register pair. This event can be a
Special Event Trigger.
