TIMER2 MODULE
The Timer2 module timer has the following features:
8-bit timer (TMR2 register)
- Readable and writable
8-bit period register (PR2)
- Readable and writable
Software programmable prescaler (1:1, 1:4, 1:16)
Software programmable postscaler (1:1 to 1:16)
Interrupt on match (TMR2 = PR2)
Timer2 can be used by SSP and CCP
Timer2 has a control register, shown in Register 6-1.
Timer2 can be shut off by clearing control bit TMR2ON
(T2CON<2>) to minimize power consumption.
Figure 6-1 is a simplified block diagram of the Timer2
module.
Additional information on timer modules is available in
the PICmicro Mid-Range Reference Manual,
(DS33023).
