Note:

x: Immediate data

m: Data memory address

A: Accumulator

i: 0~7 number of bits

addr: Program memory address

Ö: Flag is affected

-: Flag is not affected

(1): If a loading to the PCL register occurs, the execution cycle of instructions will be delayed for one more cycle

(four system clocks).

(2): If a skipping to the next instruction occurs, the execution cycle of instructions will be delayed for one more

cycle (four system clocks). Otherwise the original instruction cycle is unchanged.

(3): (1) and (2)

(4): The flags may be affected by the execution status. If the Watchdog Timer is cleared by executing the

²CLR WDT1² or ²CLR WDT2² instruction, the TO and PDF are cleared.

Otherwise the TO and PDF flags remain unchanged.
