Therefore, the maximum baud rate that can be received at the transfer destination is as follows.
Similarly, the maximum allowable value can be obtained as follows.
Therefore, the minimum baud rate that can be received at the transfer destination is as follows.
The allowable baud rate error of UARTBn and the transfer destination can be obtained as follows from the
expressions described above for computing the minimum and maximum baud rate values.
Remarks 1. The reception precision depends on the number of bits in one frame, the base clock frequency,

and the division ratio (k). The higher the base clock frequency and the larger the division ratio
(k), the higher the precision.
