The PIC16F630/676 differentiates between various
kinds of Reset:
a)
b)
c)
d)
e)
f)
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
• MCLR Reset
• WDT Reset
• WDT Reset during Sleep
• Brown-out Detect (BOD)

They are not affected by a WDT wake-up, since this is
viewed as the resumption of normal operation. TO and
PD bits are set or cleared differently in different Reset
situations as indicated in Table 9-4. These bits are
used in software to determine the nature of the Reset.
See Table 9-7 for a full description of Reset states of all
registers.
A simplified block diagram of the On-Chip Reset Circuit
is shown in Figure 9-4.
The MCLR Reset path has a noise filter to detect and
ignore small pulses. See Table 12-4 in Electrical
Specifications Section for pulse-width specification.
See Table 9-3 for time-out situations.
