Asynchronous mode:
00: Internal baud rate generator (SCK3 pin functions as
an I/O port)
01: Internal baud rate generator (Outputs a clock of the
same frequency as the bit rate from the SCK3 pin)
10: External clock (Inputs a clock with a frequency 16
times the bit rate from the SCK3 pin)
11: Reserved
Clock synchronous mode:
00: Internal clock (SCK3 pin functions as clock output)
01: Reserved
10: External clock (SCK3 pin functions as clock input)
11: Reserved
