• When the DINC instruction is executed while the data in the device specified by (d) is 2147483647, -2147483648 is stored
in the device specified by (d).
• When the DINC_U instruction is executed while the data in the device specified by (d) is 4294967295, 0 is stored in the
device specified by (d).
