Notes: 1.

φ w/2 clock in active (medium-speed/high-speed) mode and sleep mode

φ w clock in subactive mode and subsleep mode

In subactive or subsleep mode, SCI3 can be operated when CPU clock is

φw/2 only.

Table 10.5 shows the maximum bit rate for each frequency. The values shown are for active (high-

speed) mode.
