The Timer4 module timer has the following features:
• 8-bit timer (TMR4 register)
• 8-bit period register (PR4)
• Readable and writable (both registers)
• Software programmable prescaler (1:1, 1:4, 1:16)
• Software programmable postscaler (1:1 to 1:16)
• Interrupt on TMR4 match of PR4
Timer4 has a control register shown in Register 15-1.
Timer4 can be shut-off by clearing control bit, TMR4ON
(T4CON<2>), to minimize power consumption. The
prescaler and postscaler selection of Timer4 are also
controlled by this register. Figure 15-1 is a simplified
block diagram of the Timer4 module.

Timer4 can be used as the PWM time base for the
PWM mode of the CCP module. The TMR4 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
T4CKPS1:T4CKPS0 (T4CON<1:0>). The match out-
put of TMR4 goes through a 4-bit postscaler (which
gives a 1:1 to 1:16 scaling inclusive) to generate a
TMR4 interrupt, latched in flag bit, TMR4IF (PIR3<3>).
The prescaler and postscaler counters are cleared
when any of the following occurs:
• a write to the TMR4 register
• a write to the T4CON register
• any device Reset (Power-on Reset, MCLR Reset,
TMR4 is not cleared when T4CON is written.
Watchdog Timer Reset or Brown-out Reset)
