454CHAPTER 19 SERIAL INTERFACE CHANNEL 2(ii) Generation of baud rate transmit/receive clock by means of external clock from ASCK pinThe transmit/receive clock is generated by scaling the clock input from the ASCK pin. The baud rategenerated from the clock input from the ASCK pin is obtained with the following expression.[Baud rate] = [Hz]f ASCK : Frequency of clock input to ASCK pink : Value set in MDL0 to MDL3 (0 ≤ k ≤ 14)Table 19-6.
