Accesses to port H and J registers and the on-chip motor control PWM timer module are
performed in four states. The data bus width is 8 or 16 bits depending on the internal I/O register.
Access timing for port H and J registers and the on-chip motor control PWM timer module is
shown in figure 2-24, and the pin states are shown in figure 2-25.
