13.0
The PIC17C75X has a wealth of timers and time-based
functions to ease the implementation of control applica-
tions. These time-base functions include three PWM
outputs and four Capture inputs.
Timer1 and Timer2 are two 8-bit incrementing timers,
each with an 8-bit period register (PR1 and PR2
respectively) and separate overflow interrupt flags.
Timer1 and Timer2 can operate either as timers (incre-
ment on internal Fosc/4 clock) or as counters (incre-
ment on falling edge of external clock on pin
RB4/TCLK12). They are also software configurable to
operate as a single 16-bit timer/counter. These timers
are also used as the time-base for the PWM (Pulse
Width Modulation) modules.
Timer3 is a 16-bit timer/counter which uses the TMR3H
and TMR3L registers. Timer3 also has two additional
registers (PR3H/CA1H: PR3L/CA1L) that are config-
urable as a 16-bit period register or a 16-bit capture
register. TMR3 can be software configured to incre-
ment from the internal system clock (F
an external signal on the RB5/TCLK3 pin. Timer3 is the
time-base for all of the 16-bit captures.

Six other registers comprise the Capture2, Capture3,
and Capture4 registers (CA2H:CA2L, CA3H:CA3L,
and CA4H:CA4L).
Figure 13-1, Figure 13-2, and Figure 13-3 are the con-
trol registers for the operation of Timer1, Timer2, and
Timer3, as well as PWM1, PWM2, PWM3, Capture1,
Capture2, Capture3, and Capture4.
Table 13-1 shows the Timer resource requirements for
these time-base functions. Each timer is an open
resource so that multiple functions may operate with it.
