Section 2 CPU
2.5
The H8SX CPU has the internal registers shown in figure 2.9. There are two types of registers:
general registers and control registers. The control registers are the 32-bit program counter (PC),
8-bit extended control register (EXR), 8-bit condition-code register (CCR), 32-bit vector base
register (VBR), 32-bit short address base register (SBR), and 64-bit multiply-accumulate register
(MAC).
