EP7311
High-Performance, Low-Power System on Chip
Pin Multiplexing
The following table shows the pin multiplexing of the
MCP, SSI2 and the CODEC. The selection between SSI2
and the CODEC is controlled by the state of the SERSEL
bit in SYSCON2. The choice between the SSI2, CODEC,
and the MCP is controlled by the MCPSEL bit in
SYSCON3 (see the EP73xx User’s Manual for more
information).
