Description
Asynchronous Clock Source Select
When an average transfer rate is selected, the
base clock is set automatically regardless of the
ABCS value. Note that average transfer rates are
not supported for operating frequencies other than
10.667 MHz and 16 MHz.
The ACS0 to ACS0 settings are valid when the
external clock input is selected (CKE in SCR = 0)
in asynchronous mode (C/A in SMR = 0).
