3.2.3 Special function registers (SFRs)
manipulation instructions. The manipulatable bit units, 1, 8, and 16, depend on the special function register type.
66
Unlike a general-purpose register, each special function register has a special function.
SFRs are allocated to the FF00H to FFFFH area.
Special function registers can be manipulated like general-purpose registers, using operation, transfer and bit
Each manipulation bit unit can be specified as follows.
Table 3-6 gives a list of the special function registers. The meanings of items in the table are as follows.
1-bit manipulation
Describe the symbol reserved by the assembler for the 1-bit manipulation instruction operand (sfr.bit).
This manipulation can also be specified with an address.
8-bit manipulation
Describe the symbol reserved by the assembler for the 8-bit manipulation instruction operand (sfr).
This manipulation can also be specified with an address.
16-bit manipulation
Describe the symbol reserved by the assembler for the 16-bit manipulation instruction operand (sfrp).
When specifying an address, describe an even address.
Symbol
Symbol indicating the address of a special function register. It is a reserved word in the RA78K0, and is defined
as an sfr variable using the #pragma sfr directive in the CC78K0. When using the RA78K0, ID78K0-NS,
ID78K0, or SM78K0, symbols can be written as an instruction operand.
R/W
Indicates whether the corresponding special function register can be read or written.
R/W: Read/write enable
R:
W:
Manipulatable bit units
Indicates the manipulatable bit unit (1, 8, or 16). “ ” indicates a bit unit for which manipulation is not possible.
After reset
Indicates each register status upon RESET input.
