12.0
The PIC17C4X has a wealth of timers and time-based
functions to ease the implementation of control applica-
tions. These time-base functions include two PWM out-
puts and two Capture inputs.
Timer1 and Timer2 are two 8-bit incrementing timers,
each with a period register (PR1 and PR2 respectively)
and separate overflow interrupt flags. Timer1 and
Timer2 can operate either as timers (increment on
internal Fosc/4 clock) or as counters (increment on fall-
ing edge of external clock on pin RB4/TCLK12). They
are also software configurable to operate as a single
16-bit timer. These timers are also used as the
time-base for the PWM (pulse width modulation) mod-
ule.

Timer3 is a 16-bit timer/counter consisting of the
TMR3H and TMR3L registers. This timer has four other
associated registers. Two registers are used as a 16-bit
period
(PR3H/CA1H:PR3L/CA1L). The other two registers are
strictly the Capture2 registers (CA2H:CA2L). Timer3 is
the time-base for the two 16-bit captures.
TMR3 can be software configured to increment from
the internal system clock or from an external signal on
the RB5/TCLK3 pin.
Figure 12-1 and Figure 12-2 are the control registers
for the operation of Timer1, Timer2, and Timer3, as well
as PWM1, PWM2, Capture1, and Capture2.
