TIMER2 MODULE

The Timer2 module incorporates the following features:

• 8-bit Timer and Period registers (TMR2 and PR2,

respectively)

• Readable and writable (both registers)

• Software programmable prescaler (1:1, 1:4, 1:16,

and 1:64)

• Software programmable postscaler (1:1 to 1:16)

• Interrupt on TMR2 match with PR2

See Figure 18-1 for a block diagram of Timer2.
