32.9.5 SSC Transmit Clock Mode Register
Name:
SSC_TCMR
Address:
0x40004018
Access:
Read-write 
This register can only be written if the WPEN bit is cleared in 
• CKS: Transmit Clock Selection 
• CKO: Transmit Clock Output Mode Selection
• CKI: Transmit Clock Inversion
0 = The data outputs (Data and Frame Sync signals) are shifted out on Transmit Clock falling edge. The Frame sync signal 
input is sampled on Transmit clock rising edge.
1 = The data outputs (Data and Frame Sync signals) are shifted out on Transmit Clock rising edge. The Frame sync signal 
input is sampled on Transmit clock falling edge.
CKI affects only the Transmit Clock and not the output clock signal.
