5.2.3 Special function register (SFR)
bit manipulation instructions. Manipulatable bit units, 1, 8, and 16, depend on the special function register type.
Unlike a general-purpose register, each special function register has special functions.
It is allocated in the FF00H to FFFFH area.
The special function register can be manipulated like the general-purpose register, with the operation, transfer and
Each manipulation bit unit can be specified as follows.
• 1-bit manipulation
• 8-bit manipulation
• 16-bit manipulation
Table 5-5 gives a list of special function registers. The meaning of items in the table is as follows.
• Symbol
• R/W
• Manipulatable bit units
• After reset
Describe the symbol reserved with assembler for the 1-bit manipulation instruction operand (sfr.bit).
This manipulation can also be specified with an address.
Describe the symbol reserved with assembler for the 8-bit manipulation instruction operand (sfr).
This manipulation can also be specified with an address.
Describe the symbol reserved with assembler for the 16-bit manipulation instruction operand (sfrp).
When addressing an address, describe an even address.
Symbol indicating the address of a special function register. It is a reserved word in the RA78K0, and is defined
as the sfr variable by the #pragma sfr direction in the CC78K0. When using the RA78K0, ID78K0-NS, ID78K0,
or SM78K0, symbols can be written as an instruction operand.
Indicates whether the corresponding special function register can be read or written.
R/W: Read/write enable
R:
W:
Indicates the manipulatable bit unit (1, 8, or 16). “–” indicates a bit unit for which manipulation is not possible.
Indicates each register status upon RESET input.
