Specify same type of devices in and . The device number of should be smaller than or equal to the
device number of .
If the device number of is larger than the device number of , only one device specified in is reset.
2. When specifying high-speed counters (C235 to C255)
The ZRST instruction is handled as the 16-bit type, but 32-bit counters can be specified in and .
