When BR0CR<BR0ADDE> = 1
The baud rate generator is the circuit which generates transmission/receiving clock
The input clock to the baud rate generator, φT0, φT2, φT8 or φT32, is generated by
The baud rate generator includes a frequency divider, which divides the frequency by
The transfer rate is determined by the settings of BR0CR<BR0ADDE, BR0S3:0> and
When BR0CR<BR0ADDE> = 0
The N + (16 − K)/16 division function is not available in I/O interface mode. Clear
The method for calculating the transfer rate when the baud rate generator is used is
