The switch drain and source columns indicate which physical balls are involved in a particular current source function. The feedback column indicates which feedback
channel is used to connect the I/O back to the AFE, which subsequently affects which op amps and comparators can be used with that I/O.
To request particular I/O, write to
register; each bit corresponds to one sink I/O pair.
contains a status flag, and if all
requests were granted, should be equal to
Several different sub-modes are available; these modes define the behavior of the 0 and 1 states of the I/O. Each I/O port has a register,
which controls whether the I/O is in the 0 or 1 state. The following table maps the
against the two values of the
register.
