2.4 Register
Configuration
The H8S/2000 CPU has the internal registers shown in figure 2.6. There are two types of registers:
general registers and control registers. Control registers are a 24-bit program counter (PC), an 8-bit
extended control register (EXR), and an 8-bit condition code register (CCR).
