Serial Interfaces
The EP7211 offers the following serial interfaces in addition to the two UARTs.
The inputs/outputs of three of the serial synchronous interfaces (MCP, codec, and SSI2) are
multiplexed onto a single set of external interface pins. If the MCPSEL bit of SYSCON3 is low, then
either SSI2 or the codec interface will be selected to connect to the external pins. When Bit 0 of
SYSCON2 (SERSEL) is high, then the codec is connected to the external pins, when low the
master/slave SSI2 is connected to these pins. When the MCPSEL bit is set high, the MCP interface
is connected to the external pins. On power up, both the MCPSEL and SERSEL bits are reset low,
thus the master/slave SSI2 will be connected to these pins (and configured for slave mode operation
to avoid external drive clashes).
The following table contains pin definition information for the three multiplexed interfaces.
NOTE:
The internal names given to each of the three interfaces are unique to help differentiate them from
each other. The sections below that describe each of the three interfaces will use their respective
unique internal pin names for clarity.
