3.2.4 Special function registers (SFRs)
instructions. The manipulable bit units, 1, 8, and 16, depend on the SFR type.
68
Unlike a general-purpose register, each SFR has a special function.
SFRs are allocated to the FFF00H to FFFFFH area.
SFRs can be manipulated like general-purpose registers, using operation, transfer, and bit manipulation
Each manipulation bit unit can be specified as follows.
• 1-bit manipulation
• 8-bit manipulation
• 16-bit manipulation
Table 3-5 gives a list of the SFRs. The meanings of items in the table are as follows.
• Symbol
• R/W
• Manipulable bit units
• After reset
Caution Do not access addresses to which SFRs are not assigned.
Remark For extended SFRs (2nd SFRs), see 3.2.5 Extended special function registers (2nd SFRs: 2nd
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.
Describe the symbol reserved by the assembler for the 8-bit manipulation instruction operand (sfr). This
manipulation can also be specified with an address.
Describe the symbol reserved by the assembler for the 16-bit manipulation instruction operand (sfrp). When
specifying an address, describe an even address.
Symbol indicating the address of a special function register. It is a reserved word in the RA78K0R, and is
defined as an sfr variable using the #pragma sfr directive in the CC78K0R.
ID78K0R-QB, and SM+ for 78K0R, symbols can be written as an instruction operand.
Indicates whether the corresponding SFR can be read or written.
R/W: Read/write enable
R: Read only
W: Write only
“√” indicates the manipulable bit unit (1, 8, or 16). “−” indicates a bit unit for which manipulation is not possible.
Indicates each register status upon reset signal generation.
