7.1.2 On-Chip Support Module Access Timing
The on-chip support modules, except for HCAN, MMT, and POE, 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. For details, refer to appendix A, On-Chip I/O Register. Figure 7.2 shows access timing
for the on-chip supporting modules.
