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).
The following table shows the pins that have been multiplexed
in the EP7311.
