2.1
2. Central Processing Unit (CPU)
Data Registers (R0, R1, R2, and R3)
R0 is a 16-bit register for transfer, arithmetic, and logic operations. The same applies to R1 to R3. R0 can be split
into high-order bits (R0H) and low-order bits (R0L) to be used separately as 8-bit data registers. R1H and R1L are
analogous to R0H and R0L. R2 can be combined with R0 and used as a 32-bit data register (R2R0). R3R1 is
analogous to R2R0.
2.2
Address Registers (A0 and A1)
A0 is a 16-bit register for address register indirect addressing and address register relative addressing. It is also
used for transfer, arithmetic, and logic operations. A1 is analogous to A0. A1 can be combined with A0 and as a 32bit address register (A1A0).
2.3
Frame Base Register (FB)
FB is a 16-bit register for FB relative addressing.
2.4
Interrupt Table Register (INTB)
INTB is a 20-bit register that indicates the start address of an interrupt vector table.
2.5
Program Counter (PC)
PC is 20 bits wide and indicates the address of the next instruction to be executed.
2.6
User Stack Pointer (USP) and Interrupt Stack Pointer (ISP)
The stack pointers (SP), USP, and ISP, are each 16 bits wide. The U flag of FLG is used to switch between
USP and ISP.
2.7
Static Base Register (SB)
SB is a 16-bit register for SB relative addressing.
2.8
Flag Register (FLG)
FLG is an 11-bit register indicating the CPU state.
2.8.1
Carry Flag (C)
The C flag retains carry, borrow, or shift-out bits that have been generated by the arithmetic and logic unit.
2.8.2
Debug Flag (D)
The D flag is for debugging only. Set it to 0.
2.8.3
Zero Flag (Z)
The Z flag is set to 1 when an arithmetic operation results in 0; otherwise to 0.
2.8.4
Sign Flag (S)
The S flag is set to 1 when an arithmetic operation results in a negative value; otherwise to 0.
2.8.5
Register Bank Select Flag (B)
Register bank 0 is selected when the B flag is 0. Register bank 1 is selected when this flag is set to 1.
2.8.6
Overflow Flag (O)
The O flag is set to 1 when an operation results in an overflow; otherwise to 0.

2.8.7
2. Central Processing Unit (CPU)
Interrupt Enable Flag (I)
The I flag enables maskable interrupts.
Interrupt are disabled when the I flag is set to 0, and are enabled when the I flag is set to 1. The I flag is set to 0
when an interrupt request is acknowledged.
2.8.8
Stack Pointer Select Flag (U)
ISP is selected when the U flag is set to 0; USP is selected when the U flag is set to 1.
The U flag is set to 0 when a hardware interrupt request is acknowledged or the INT instruction of software
interrupt numbers 0 to 31 is executed.
2.8.9
Processor Interrupt Priority Level (IPL)
IPL is 3 bits wide and assigns processor interrupt priority levels from level 0 to level 7.
If a requested interrupt has higher priority than IPL, the interrupt is enabled.
2.8.10
Reserved Bit
If necessary, set to 0. When read, the content is undefined.

R8C/24 Group
Figure 3.1 is a Memory Map of R8C/24 Group. The R8C/24 group has 1 Mbyte of address space from addresses
00000h to FFFFFh.
The internal ROM is allocated lower addresses, beginning with address 0FFFFh. For example, a 48-Kbyte internal
ROM area is allocated addresses 04000h to 0FFFFh.
The fixed interrupt vector table is allocated addresses 0FFDCh to 0FFFFh. They store the starting address of each
interrupt routine.
The internal RAM is allocated higher addresses, beginning with address 00400h. For example, a 2-Kbyte internal
RAM area is allocated addresses 00400h to 00BFFh. The internal RAM is used not only for storing data but also
for calling subroutines and as stacks when interrupt requests are acknowledged.
Special function registers (SFRs) are allocated addresses 00000h to 002FFh. The peripheral function control
registers are allocated here. All addresses within the SFR, which have nothing allocated are reserved for future use
and cannot be accessed by users.

NOTES:
1. VCC = 2.7 to 5.5 V at Topr = 0 to 60°C, unless otherwise specified.
2. Definition of programming/erasure endurance
The programming and erasure endurance is defined on a per-block basis.
If the programming and erasure endurance is n (n = 100 or 10,000), each block can be erased n times. For example, if 1,024
1-byte writes are performed to block A, a 1 Kbyte block, and then the block is erased, the programming/erasure endurance
still stands at one.
However, the same address must not be programmed more than once per erase operation (overwriting prohibited).
3. Endurance to guarantee all electrical characteristics after program and erase. (1 to Min. value can be guaranteed).
4. In a system that executes multiple programming operations, the actual erasure count can be reduced by writing to sequential
addresses in turn so that as much of the block as possible is used up before performing an erase operation. For example,
when programming groups of 16 bytes, the effective number of rewrites can be minimized by programming up to 128 groups
before erasing them all in one operation. It is also advisable to retain data on the erase count of each block and limit the
number of erase operations to a certain number.
5. If an error occurs during block erase, attempt to execute the clear status register command, then execute the block erase
command at least three times until the erase error does not occur.
6. Customers desiring program/erase failure rate information should contact their Renesas technical support representative.
7. The data hold time includes time that the power supply is off or the clock is not supplied.

4. Standard of block A and block B when program and erase endurance exceeds 1,000 times. Byte program time to 1,000 times
is the same as that in program ROM.
5. In a system that executes multiple programming operations, the actual erasure count can be reduced by writing to sequential
