PIC18F47J53 FAMILY
15.0 TIMER3/5 MODULE
The Timer3/5 timer/counter modules incorporate these
features:
• Software selectable operation as a 16-bit timer or
counter
• Readable and writable 8-bit registers (TMRxH
and TMRxL)
• Selectable clock source (internal or external) with
device clock or Timer1 oscillator internal options
• Interrupt-on-overflow
• Module Reset on ECCP Special Event Trigger
Note: Throughout this section, generic references
are used for register and bit names that are the
same – except for an ‘x’ variable that indicates
the item’s association with the Timer3 or
Timer5 module. For example, the control reg-
ister is named TxCON, and refers to T3CON
and T5CON.
A simplified block diagram of the Timer3/5 module is
shown in Figure 15-1.
The Timer3/5 module is controlled through the TxCON
register (Register 15-1). It also selects the clock source
options for the ECCP modules. (For more information,
see Section 19.1.1 “ECCP Module and Timer
Resources”.)
The FOSC clock source should not be used with the
ECCP capture/compare features. If the timer will be
used with the capture or compare features, always
select one of the other timer clocking options.
