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).
The Timer2/4/6 modules incorporate the following
features:
• 8-bit Timer and Period registers (TMRx and PRx,
• Readable and writable (both registers)
• Software programmable prescaler (1:1, 1:4, 1:16
• Software programmable postscaler (1:1 to 1:16)
• Interrupt on TMRx match with PRx, respectively
• Optional use as the shift clock for the MSSPx

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.
