21.0 TIMER2/4/6 MODULES

There are up to three identical Timer2-type modules

available. To maintain pre-existing naming conventions,

the Timers are called Timer2, Timer4 and Timer6 (also

Timer2/4/6).

Note:

The ‘x’ variable used in this section is used

to designate Timer2, Timer4, or Timer6.

For example, TxCON references T2CON,

T4CON, or T6CON. PRx references PR2,

PR4, or PR6.

The Timer2/4/6 modules incorporate the following

features:

• 8-bit Timer and Period registers (TMRx and PRx,

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 TMRx match with PRx, respectively

• Optional use as the shift clock for the MSSPx

modules (Timer2 only)

See Figure 21-1 for a block diagram of Timer2/4/6.
