1.2 Registers

Figure 1-3 shows the register structure of the H8/300 CPU. There are sixteen 8-bit general

registers (R0H, R0L, ..., R7H, R7L), which can also be accessed as eight 16-bit registers (R0

to R7). There are two control registers: the 16-bit program counter (PC) and the 8-bit

condition code register (CCR).
