20.2.8
A write to the OSCCON register is intentionally made
difficult because it controls clock switching and clock
scaling.
To write to the OSCCON low byte, the following code
sequence must be executed without any other
instructions in between:
Byte write is allowed for one instruction cycle. Write the
desired value or use bit manipulation instruction.
To write to the OSCCON high byte, the following
instructions must be executed without any other
instructions in between:
Byte write is allowed for one instruction cycle. Write the
desired value or use bit manipulation instruction.

The PIC18F1220/1320 differentiates between various
kinds of Reset:
a)
b)
c)
d)
e)
f)
g)
h)
Different registers are affected in different ways by var-
ious Reset conditions. Most registers are not affected
by a WDT wake-up, since this is viewed as the resump-
tion of normal operation. Status bits from the RCON
register are set or cleared differently in different Reset
situations, as indicated in Table 20-5. These bits are
used in software to determine the nature of the Reset.
A block diagram of the on-chip Reset circuit is shown in
Figure 20-2.
A MCLR noise filter is provided in the MCLR Reset
path. The filter detects and ignores small pulses.
Internally generated Resets do not drive MCLR pin low.
