Therefore, the maximum baud rate that can be received by the destination is as follows.
Similarly, obtaining the following maximum allowable transfer rate yields the following.
Therefore, the minimum baud rate that can be received by the destination is as follows.
Obtaining the allowable baud rate error for UARTCn and the destination from the above-described equations
for obtaining the minimum and maximum baud rate values yields the following.
Remarks 1. The reception accuracy depends on the bit count in 1 frame, the input clock
