22.0 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 refer-

ences 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 22-1 for a block diagram of Timer2/4/6.
