R8C/22 Group, R8C/23 Group 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 bit (R0H) and low-order bit (R0L) to be used separately as 8-bit data registers. The same applies to R1H and R1L as R0H and R0L. R2 can be combined with R0 to be used as a 32-bit data register (R2R0). The same applies R3R1 as R2R0. 2.

R8C/22 Group, R8C/23 Group 2.8.7 2. Central Processing Unit (CPU) Interrupt Enable Flag (I) The I flag enables a maskable interrupt. An interrupt is 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 internal ROM is allocated lower addresses, beginning with address 0FFFFh. For example, a 48-Kbyte internal ROM 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.
