Table 7-1. Special Function Registers (SFRs) (4/5)
Notes 1.
When the LOCATION 0 instruction is executed. When the LOCATION 0FH instruction is executed,
F0000H is added to each address.
2.
A write operation can be performed only with special instructions MOV STBC,#byte and MOV
WDM,#byte. Other instructions cannot perform a write operation.
