• Asynchronous mode
00: On-chip baud rate generator
01: On-chip 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
• Clocked synchronous mode
00: On-chip clock (SCK3 pin functions as clock output)
