Affected flag(s)
Preclear watchdog timer
The PD, TO flags, WDT and the WDT Prescaler are all cleared (re-count
from zero) if the other preclear WDT instruction has been executed. Execu-
tion only of this instruction without the other preclear instruction sets the
indicated flag, which implies that this instruction is executed and the PD
and TO flags remain unchanged.
WDT & WDT Prescaler ¬ 00H*
PD & TO ¬ 0*

Complement data memory
Each bit of the specified data memory is logically complemented (1¢s comple-
ment). Bits which previously contained a one are changed to zero and
vice-versa.
