2.4
The H8S/2600 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 register (EXR), an 8-bit condition code register (CCR), and a 64-bit multiply-accumulate
register (MAC).
