R8C/32D Group 2. 2. Central Processing Unit (CPU) Central Processing Unit (CPU) Figure 2.1 shows the CPU Registers. The CPU contains 13 registers. R0, R1, R2, R3, A0, A1, and FB configure a register bank. There are two sets of register bank.
PAGE 12
R8C/32D 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 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.
PAGE 13
R8C/32D Group 2.8.7 2. Central Processing Unit (CPU) Interrupt Enable Flag (I) The I flag enables maskable interrupts. Interrupts 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.

R8C/32D Group 3. 3. Memory Memory 3.1 R8C/32D Group Figure 3.1 is a Memory Map of R8C/32D Group. The R8C/32D Group has a 1-Mbyte address space from addresses 00000h to FFFFFh. The internal ROM (program ROM) is allocated lower addresses, beginning with address 0FFFFh. For example, a 16-Kbyte internal ROM area is allocated addresses 0C000h to 0FFFFh. The fixed interrupt vector table is allocated addresses 0FFDCh to 0FFFFh. The starting address of each interrupt routine is stored here.
