Access to On-Chip Peripheral Modules

On-chip peripheral modules are accessed in two states or three states. The data bus width is 8 bits,

so access is by byte size only. This means that for accessing word data, two instructions must be

used.

Two-State Access to On-Chip Peripheral Modules: Figure 2.12 shows the operation timing in

the case of two-state access to an on-chip peripheral module.
