19.0 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, respectively
• Optional use as the shift clock for the MSSP
modules
See Figure 19-1 for a block diagram of Timer2.
