The frame sync and clock signals generated from ACM block can be routed internally to one of the halvesof SPORT1. So, if we choose SPORT1_A as ACM interface (EPSACM=0), then we can also use SPMUX features at SPORT1_B to import CLK and FS.
Up until here, it is clear!
My question is:
There will be 16 ADC-DAC combo ccts in our design.
SPORT1_A will be used in receiving and SPORT1_B will be used in transmitting by using the ACM module.
Is this possible?
And in the document "ADSP-BF60x Blackfin Processor Hardware Reference, Revision 0.5" on page 26-15 it says:
"There are some limitations on use of SPMUX logic when a SPORT is interfaced with an ACM
module of the processor. Refer to the ACM chapter for more details."
But I couldn't find the limitations. Could you explain it or show me where it mentions about the limitations in the document.
Thanks.
