EXTERNAL CLOCK IN
In EC mode, users may directly drive the PIC16C745/
765 provided that this external clock source meets the
AC/DC timing requirements listed in Section 17.4.
Figure 13-2 below shows how an external clock circuit
should be configured.

E4 MODE
In E4 mode, a PLL module is switched on in-line with
the clock provided to OSC1. The output of the PLL
drives FINT.

RESET
The PIC16CXX differentiates between various kinds of
RESET:
Power-on Reset (POR)
MCLR Reset during normal operation
MCLR Reset during SLEEP
WDT Reset (normal operation)
Brown-out Reset (BOR)
Some registers are not affected in any RESET condi-
tion; their status is unknown on POR and unchanged in
any other RESET. Most other registers are reset to a
“RESET state” on POR, on the MCLR and WDT Reset,
on MCLR Reset during SLEEP, and on BOR. The TO
and PD bits are set or cleared differently in different
RESET situations as indicated in Table 13-4. These
bits are used in software to determine the nature of the
RESET. See Table 13-7 for a full description of RESET
states of all registers.
A simplified block diagram of the on-chip RESET circuit
is shown in Figure 13-4.
The PICmicro devices have a MCLR noise filter in the
MCLR Reset path. The filter will detect and ignore
small pulses.
It should be noted that a WDT Reset does not drive
MCLR pin low.
