Always zero.
When 1, the input SDI signal (if present) is discarded and the shield
generates its own SDI signal on the SDI output connector. When 0,
the input signal is passed through to the output if present, or the
shield generates its own SDI signal if not.
When 1, the last received incoming tally data is immediately copied
over to the override tally data register. Automatically cleared
by hardware.
When 1, tally data is overridden with the user supplied data. When 0,
input tally data is passed through to the output unmodified.
When 1, control data is overridden with the user supplied data.
When 0, input control data is passed through to the output
unmodified.
