serial data signal for the interface.
Note: If AB1D function is selected but not used, tie
AB1D high.
I/O ACCESS.bus 2 Serial Clock. This is the serial clock for
the interface.
Note: If AB2C function is selected but not used, tie
AB2C high.
I/O ACCESS.bus 2 Serial Data. This is the bidirectional
serial data signal for the interface.
Note: If AB2D function is selected but not used, tie
AB2D high.
