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 10-4 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 by 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 on
Brown-out Reset (BOR). They are not affected by a
WDT Wake-up from SLEEP, which is viewed as the
resumption of normal operation. The TO and PD bits
are set or cleared depending on the reset situation, as
indicated in Table 10-4. These bits are used in software
to determine the nature of the reset. See Table 10-6 for
a full description of reset states of all registers.
A simplified block diagram of the on-chip reset circuit is
shown in Figure 10-5.
The PICmicro devices have a MCLR noise filter in the
MCLR reset path. The filter will ignore small pulses.
However, a valid MCLR pulse must meet the minimum
pulse width (TmcL, Specification #30).
No internal reset source (WDT, BOR, POR) willdrive
the MCLR pin low.
