3.0
The PIC18F6525/6621/8525/8621 devices differentiate
between various kinds of Reset:
a)
b)
c)
d)
e)
f)
g)
h)
Most registers are unaffected by a Reset. Their status
is unknown on POR and unchanged by all other
Resets. The other registers are forced to a “Reset
state” on Power-on Reset, MCLR, WDT Reset, Brown-
out Reset, MCLR Reset during Sleep and by the
RESET instruction.

Most registers are not affected by a WDT wake-up
since this is viewed as the resumption of normal oper-
ation. Status bits from the RCON register, RI, TO, PD,
POR and BOR, are set or cleared differently in different
Reset situations as indicated in Table 3-2. These bits
are used in software to determine the nature of the
Reset. See Table 3-3 for a full description of the Reset
states of all registers.
A simplified block diagram of the On-Chip Reset Circuit
is shown in Figure 3-1.
The Enhanced MCU devices have a MCLR noise filter
in the MCLR Reset path. The filter will detect and
ignore small pulses. The MCLR pin is not driven low by
any internal Resets, including the WDT.
