(2) Symbol definition of register file
An error occurs if a register file address is directly specified as a numeral by the operand “rf” of the “PEEK
WR, rf” or “POKE rf, WR” instruction if the 17K Series Assembler (RA17K) is being used.
Therefore, the addresses of the register file must be defined in advance as symbols.
To define the addresses of the control registers as symbols, define them as the addresses 80H-BFH of BANK0.
The portion of the register file overlapping the data memory (40H-7FH), however, can be defined as symbols
as is.
