g)
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)
• MCLR Reset
• WDT Reset
• Brown-out Reset (BOR)

Preliminary
Most registers 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 3-6.
These bits are used in software to determine the nature
of the Reset.
A simplified block diagram of the On-Chip Reset Circuit
is shown in Figure 3-1.
The MCLR Reset path has a noise filter to detect and
ignore small pulses. See Section 28.0 “Electrical
Specifications” for pulse width specifications.
