Section 2 CPU
2.9
2.9.1
The H8/300H CPU operates according to the system clock ( ). The interval from one rise of the
system clock to the next rise is referred to as a “state.” A memory cycle or bus cycle consists of
two or three states. The CPU uses different methods to access on-chip memory, the on-chip
supporting modules, and the external address space. Access to the external address space can be
controlled by the bus controller.
2.9.2
On-chip memory is accessed in two states. The data bus is 16 bits wide, permitting both byte and
word access. Figure 2.14 shows the on-chip memory access cycle. Figure 2.15 indicates the pin
states.
