R8C/2H Group, R8C/2J 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.
R8C/2H Group, R8C/2J 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.
R8C/2H Group, R8C/2J Group 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.
