1. General Function
The main functions of the PH-M22 circuit card are:
To collect the key setting information on the TOPU of the ISW and send the information to the ISW/
the other LNs, depending on the ISEL key setting on the ISW.
To collect various alarm information from all the IMGs/ISW and activate MJ/MN LED on the TOPU
display.
This circuit card is used for the IMX-U system.
