Description
Reserved
These bits are always read as undefined and cannot be
modified.
Asynchronous Mode Base clock Select (valid only in
asynchronous mode)
Selects the base clock for a 1-bit period.
0: The base clock has a frequency 16 times the transfer
1: The base clock has a frequency 8 times the transfer
