Is it possible to change the bit rate by the BRR using ASC?

Latest Updated:03/26/2009

Question:

If an external clock is used in Asynchronous serial communication, is it possible to change the bit rate by the bit rate register(BRR)?

Answer:

It is impossible to change the bit rate by the BRR, if an external clock is used. If the external clock is selected by setting the CKE bit of the serial control register(SCR), the bit rate will be the external clock divided by 16.
