Notes:
27. Serial Port signals include: RMCK, OMCK, SAI_SCLK, SAI_LRCK, SAI_SDOUT, CX_SCLK, CX_L-
RCK, CX_SDOUT, CX_SDIN1-4, AD-
CIN1/2 Control
Port signals include: SCL/CCLK, SDA/CDOUT, AD0/CS, AD1/CDIN, INT, RST S/PDIF-
GPO Interface signals include: RXP0, RXP/GPO[1:7]
28. When operating RMCK above 24.576 MHz, limit the loading on the signal to 1 CMOS load.
