Features embedded in IESM board BOM

- As can be seen in the schematics and the GPC50 pin description, the modem

controller can assert the IESM LED and the IESM switch can be input to the modem

controller

- MBUS IESM boards: If the SMD 0R0 resistor R38 is moved to position R52 or R54

the LED will lit when a valid TX-packet is sent (position R52) or RX-packet is received

(position R54)
