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 0, input control data is passed through to the output
unmodified.
