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 (CKE1 in SCR = 1) in
asynchronous mode (C/A in SMR = 0).
