12.2
Timer2 also can generate an optional device interrupt.
The Timer2 output signal (TMR2-to-PR2 match)
provides
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 postscale options (from 1:1 through 1:16
inclusive) can be selected with the postscaler control
bits, T2OUTPS3:T2OUTPS0 (T2CON<6:3>).

The unscaled output of TMR2 is available primarily to
the CCP modules, where it is used as a time base for
operations in PWM mode.
Timer2 can be optionally used as the shift clock source
for the MSSP module operating in SPI mode.
Additional information is provided in Section 15.0
“Master Synchronous Serial Port (MSSP) Module”.
