Discrete Inputs - Individually dedicated logic level
3.5.3.4.6
discrete inputs shall be provided for MALF and CMPTR BIT status indicators.
(1) MALF Command - An input command to energize the MALF lamp
shall only illuminate the lamp of interest.
(2) CMPTR Command - An input command to energize the CMPTR lamp
shall illuminate both the MALF and CMPTR lamps. The CMPTR
input shall be biased to the logic 1 state. Logic levels
shall be as listed:
