these pins. When the DAISEL bit is set high, the
DAI interface is connected to the external pins. On
power up, both the DAISEL and SERSEL bits are
reset low, thus the master/slave SSI2 will be con-
nected to these pins (and configured for slave mode
operation to avoid external drive clashes).
Table 20
contains pin definition information for the
three multiplexed interfaces.
The internal names given to each of the three inter-
faces 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.
