9.2.3
For timing insensitive applications, the “RC” device
option offers additional cost savings. The RC oscillator
frequency is a function of the supply voltage, the resis-
tor (R
ing temperature. In addition to this, the oscillator
frequency will vary from unit to unit due to normal pro-
cess parameter variation. Furthermore, the difference
in lead frame capacitance between package types will
also affect the oscillation frequency, especially for low
C
variation due to tolerance of external R and C compo-
nents used. Figure 9-4 shows how the R/C combina-
tion is connected to the PIC16CXXX.

The PIC16CXXX differentiates between various kinds
of reset:
• Power-on Reset (POR)
• MCLR reset during normal operation
• MCLR reset during SLEEP
• WDT Reset (during normal operation)
• WDT Wake-up (during SLEEP)
• Brown-out Reset (BOR)
Some registers are not affected in any reset condition;
their status is unknown on POR and unchanged in any
other reset. Most other registers are reset to a “reset
state” on Power-on Reset (POR), on the MCLR and
WDT Reset, on MCLR reset during SLEEP and
Brown-out Reset (BOR). They are not affected by a
WDT Wake-up, which is viewed as the resumption of
normal operation. The TO and PD bits are set or
cleared differently in different reset situations as indi-
cated in Table 9-4. These bits are used in software to
determine the nature of the reset. See Table 9-6 for a
full description of reset states of all registers.
A simplified block diagram of the on-chip reset circuit is
shown in Figure 9-6.
The PICmicro microcontrollers have a MCLR noise fil-
ter 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.
