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. The control registers are a 24-bit program counter (PC), an
8-bit extended control register (EXR), an 8-bit condition code register (CCR), and a 64-bit
multiply-accumulate register (MAC).
