2.6.2
On-chip peripheral modules are accessed in two states or three states. The data bus width is 8 bits
or 16 bits depending on the register. For description on the data bus width and number of
accessing states of each register, refer to section 20.1, Register Addresses (Address Order).
Registers with 16-bit data bus width can be accessed by word size only. Registers with 8-bit data
bus width can be accessed by byte or word size. When a register with 8-bit data bus width is
accessed by word size, a bus cycle occurs twice. In two-state access, the operation timing is the
same as that for on-chip memory.
Figure 2.10 shows the operation timing in the case of three-state access to an on-chip peripheral
module.
