Processing details
■INC
• Adds 1 to the device designated by (D) (16-bit data).
D
b15 b0 b15
5678 (BIN)
• When INC/INCP operation is executed for the device designated by (D), whose content is 32767, the value -32768 is
stored at the device designated by (D).
■DEC
• Subtracts 1 from the device designated by (D) (16-bit data).
D
b15 b0 b15

1
• When DEC/DECP operation is executed for the device designated by (D), whose content is -32768, the value 32767 is
stored at the device designated by (D).
Operation error
• There is no operation error in the INC(P) or DEC(P) instruction.
