The Timer2 module has the following features:
• 8-bit Timer register (TMR2)
• 8-bit Period register (PR2)
• Readable and writable (both registers)
• Software programmable prescaler (1:1, 1:4, 1:16)
• Software programmable postscaler (1:1 to 1:16)
• Interrupt on TMR2 match with PR2
• SSP module optional use of TMR2 output to

Timer2 can be used as the PWM time base for the
PWM mode of the CCP module. The TMR2 register is
readable and writable, and is cleared on any device
Reset. The input clock (F
of 1:1, 1:4 or 1:16, selected by control bits,
T2CKPS<1:0> (T2CON<1:0>). The match output of
TMR2 goes through a 4-bit postscaler (which gives a
1:1 to 1:16 scaling inclusive) to generate a TMR2
interrupt, latched in flag bit, TMR2IF (PIR1<1>).
The TMR2 and PR2 registers are both directly readable
and writable. The TMR2 register is cleared on any
device Reset, while the PR2 register initializes at FFh.
The prescaler and postscaler counters are cleared
when any of the following occurs:
• A write to the TMR2 register
• A write to the T2CON register
• Any device Reset (Power-on Reset, MCLR Reset,
TMR2 is not cleared when T2CON is written.
