PIC18F87K22 FAMILY
15.2
Timer2 can also generate an optional device interrupt.
The Timer2 output signal (TMR2 to PR2 match) provides
the input for the four-bit output counter/postscaler. This
counter generates the TMR2 match interrupt flag, which
is latched in TMR2IF (PIR1<1>). The interrupt is enabled
by setting the TMR2 Match Interrupt Enable bit, TMR2IE
(PIE1<1>).
A range of 16 postscaler options (from 1:1 through 1:16
inclusive) can be selected with the postscaler control
bits, T2OUTPS<3:0> (T2CON<6:3>).

The unscaled output of TMR2 is available primarily to
the ECCP modules, where it is used as a time base for
operations in PWM mode.
Timer2 can optionally be used as the shift clock source
for the MSSP modules operating in SPI mode.
Additional information is provided in Section 21.0
“Master Synchronous Serial Port (MSSP) Module”.
