capacitors C41,
C44, C47, C48
Value 100nF
Value 4.7nF
Resistor R34
Uses 100 Ohm resistor to connect
RX_DATA_N and RX_DATA_P
The pcb provides soldering points
to add a resistor between
RX_DATA_N and RX_DATA_P,
but by default this resistor is not
fitted.
Pins A12/P12:
AWOVCL
Both pins are directly connected
to AWOVCL on the board.
A18 is connected to AWOVCL via
100 Ohm resistor. A18 and P12 are
connected to VSS.
Pin E17:
GETH0VCL
Connected directly to GETH0VCL
on the board.
Connected to GETH0VCL via 100
Ohm resistor and has a 220nF
capacitor to VSS. Provides the
possibility to connect pin E17 to
VSS via solder bridge RB5.
