The Total-AceXtreme® provides 8 user-programmable I/O signals,
DISCRETE_IO_7:0. These signals are independently programmable as inputs or
outputs and are independently controllable.
The direction and state (for outputs) of the Digital I/O signals are controllable by
means of the Total-AceXtreme’s Digital I/O Register. This register also allows the
host processor to poll the values of Digital I/O signals designated as inputs and verify
the values of signals designated as outputs. The power-on default state for
DISCRETE_IO_7:0 is as input signals.
In addition to DISCRETE_IO_7:0, The Total-AceXtreme includes two user-
programmable output-only signals, USER_OUTPUT_2:1. The power-on default state
for USER_OUTPUT_2:1 is for logic ‘0’.
