8.3.2 BIT

The BIT command sets/gets bit-based hardware input and output signals.

Typically, bit signals are controlled by the FAA20 software or are used for

factory test purposes. There are some signals that are reserved for future

use, but can be read and/or controlled by the BIT command. Examples

include X03..X00, X03E..X00E, DDAT, DDET, and ECHO. Table 13

provides descriptions for each of the 46 individual bit controls.
