16.3.9 Programmable LED D3
The phyCORE Carrier Board HD200 offers a programmable LED at
D3 for user implementations. This LED can be connected to port pin
P0.8 (TxD1) of the phyCORE-LPC2292/94 which is available via
signal GPIO0 (JP17 = closed). A low-level at port pin P0.8 causes the
LED to illuminate, LED D3 remains off when writing a high-level to
P0.8.

16.3.10 User Push Button S3
The phyCORE Carrier Board HD200 (starting with PCB revision
1179.6) offers a push button at S3 for user implementations. Jumper
JP40 connects this push button to port pin P015 (X700B3/BUS4) or
P020 (X700A4/BUS5) of the phyCORE-LPC2292/94. If the push
button is pressed the corresponding port pin will read a low level on
this input. A 4.7 kOhm pull-up resistor ensure a high level at this line
when the button is not activated.
