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
• MCLR Reset during Sleep
• WDT Reset
• Brown-out Reset (BOR)

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 14-2. These bits are
used in software to determine the nature of the Reset.
See Table 14-5 for a full description of Reset states of
all registers.
A simplified block diagram of the On-Chip Reset Circuit
is shown in Figure 14-1.
The MCLR Reset path has a noise filter to detect and
ignore small pulses. See Section 17.0 “Electrical
Specifications” for pulse-width specifications.
