Section 7 Bus Controller
7.5.2
The on-chip peripheral modules are accessed in two states. The data bus is either 8 bits or 16 bits
wide, depending on the particular internal I/O register being accessed. Figure 7.6 shows the access
timing for the on-chip peripheral modules. Figure 7.7 shows the pin states.
