No operation; Adds 1 to program counter value, and others remain unchanged.
Puts the system in clock operating mode by executing the POF instruction after executing the EPOF instruction.
Puts the system in RAM back-up state by executing the POF2 instruction after executing the EPOF instruction.
Makes the immediate after POF or POF2 instruction valid by executing the EPOF instruction.
Skips the next instruction when the P flag is “1”.
After skipping, the P flag remains unchanged.
Skips the next instruction when watchdog timer flag WDF1 is “1.” After skipping, clears (0) to the WDF1 flag.
Also, stops the watchdog timer function when executing the WRST instruction immediately after the DWDT
instruction.
Stops the watchdog timer function by the WRST instruction after executing the DWDT instruction.
Sets referring data area to pages 0 to 63 when the TABP p instruction is executed.
This instruction is valid only for the TABP p instruction.
Sets referring data area to pages 64 to 127 when the TABP p instruction is executed.
This instruction is valid only for the TABP p instruction.
Validates the voltage drop detection circuit at power down (clock operating mode and RAM back-up mode)
when VDCE pin is “H”.
