Notes 1. When the LOCATION 0 instruction is executed. Add “F0000H” to this value when the LOCATION 0FH
instruction is executed.
2. These registers can be written only by using dedicated instructions MOV STBC, #byte and MOV WDM,
#byte, and cannot be written by any other instructions.
3. The value of this register on reset differs depending on the setting of the BWD pin.
BWD = 0: 0000H
BWD = 1: 00FFH
