Section 7 Bus Controller
7.5.2
On-Chip Peripheral Module Access Timing Excluding Port H, Port J, IIC2, IEB, and
HCAN: The on-chip peripheral modules are accessed in two states except for port H, port J, IIC2,
IEB, and HCAN. The data bus width is either 8 bits or 16 bits, 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.
