16.2.3 Unsupported Features and Improper Jumper Settings
The following table contains improper jumper settings for operation of
the phyCORE-LPC2292/94 on a phyCORE Development
Board HD200. Functions configured by these settings are not
supported by the phyCORE module.
No RS-485 interface:
DB-9 plug P2B on the Carrier Board can be configured as
RS-485 interface as an alternative to the second CAN interface. The
phyCORE-LPC2292/94 does not support an RS-485 interface. For this
reason the corresponding jumper settings should never be used.
Jumper Setting Description
JP30 closed TxD signal for second serial interface routed to
pin 8 on the DB-9 plug P2B
JP33 1 + 2 RxD signal for second serial interface routed to
pin 2 on the DB-9 plug P2B

Pins X1C42, X1C47, X1D44 and X1D49 (VAGND) of the
phyCORE-LPC2292/94 are solely connected with the phyCORE
Carrier Board HD200 GND potential. This makes a separate supply
with an alternative VAGND potential impossible. Free definition of
the VAGND potential is however available in a customer application
board.
