Notes: 1. ø w/2 clock in active (medium-speed/high-speed) mode and sleep mode
Table 10.5 shows the maximum bit rate for each frequency. The values shown are for active
(high-speed) mode.
2. The value set in BRR is given by the following equation:
3. The error in table 10.3 is the value obtained from the following equation, rounded to
2. ø w clock in subactive mode and subsleep mode
3. In subactive or subsleep mode, SCI3 can be operated when CPU clock is øw/2 only.

B: Bit rate (bit/s)
N: Baud rate generator BRR setting (0 N 255)
OSC: Value of ø
n: Baud rate generator input clock number (n = 0, 2, or 3)
