This section describes the second 32-bit General Pur-
pose (GP) Timer module (Timer4/5) and associated
operational modes. Figure 11-1 depicts the simplified
block diagram of the 32-bit Timer4/5 Module.
Figure 11-2 and Figure 11-3 show Timer4/5 configured
as two independent 16-bit timers, Timer4 and Timer5,
respectively.
The Timer4/5 module is similar in operation to the
Timer 2/3 module. However, there are some differ-
ences, which are listed below:
• The Timer4/5 module does not support the ADC
• Timer4/5 can not be utilized by other peripheral

The operating modes of the Timer4/5 module are deter-
mined by setting the appropriate bit(s) in the 16-bit
T4CON and T5CON SFRs.
For 32-bit timer/counter operation, Timer4 is the LS
Word and Timer5 is the MS Word of the 32-bit timer.

For 32-bit timer operation, T5CON control
bits are ignored. Only T4CON control bits
are used for setup and control. Timer4
clock and gate inputs are utilized for the
32-bit timer module, but an interrupt is
generated with the Timer5 interrupt flag
(T5IF) and the interrupt is enabled with the
Timer5 interrupt enable bit (T5IE).
