32.9.3 SSC Receive Clock Mode Register
Name:
SSC_RCMR
Address:
0x40004010
Access:
Read-write
This register can only be written if the WPEN bit is cleared in
• CKS: Receive Clock Selection
• CKO: Receive Clock Output Mode Selection
• CKI: Receive Clock Inversion
0 = The data inputs (Data and Frame Sync signals) are sampled on Receive Clock falling edge. The Frame Sync signal
output is shifted out on Receive Clock rising edge.
1 = The data inputs (Data and Frame Sync signals) are sampled on Receive Clock rising edge. The Frame Sync signal
1 = The data inputs (Data and Frame Sync signals) are sampled on Receive Clock rising edge. The Frame Sync signal
output is shifted out on Receive Clock falling edge.
CKI affects only the Receive Clock and not the output clock signal.
