The Timer1 module is a 16-bit timer, which can serve
as the time counter for the real-time clock, or operate
as a free-running interval timer/counter.
The Timer1 module has the following unique features
over other timers:
• Can be operated from the low power 32 kHz
• Can be operated in Asynchronous Counter mode
• The external clock input (T1CK) can optionally be
The unique features of Timer1 allow it to be used for
Real Time Clock (RTC) applications. A block diagram
of Timer1 is shown in Figure 11-1.

The Timer1 module can operate in one of the following
modes:
• Timer mode
• Gated Timer mode
• Synchronous Counter mode
• Asynchronous Counter mode
In Timer and Gated Timer modes, the input clock is
derived from the internal instruction cycle clock (F
In Synchronous and Asynchronous Counter modes,
the input clock is derived from the external clock input
at the T1CK pin.
The Timer modes are determined by the following bits:
• Timer Clock Source Control bit (TCS):
• Timer Synchronization Control bit (TSYNC):
• Timer Gate Control bit (TGATE): T1CON<6>
Timer control bit setting for different operating modes
are given in the Table 11-1.
