The following configurations are possible:
Flash Addressing
J3
If Flash memory is < 2 MB, then P4.4 is used as a
standard I/O or as CAN1 receive line
open*
If Flash memory is > 2 MB, then P4.4 serves as A20
for addressing the Flash (CAN receive line must be
closed
* = Default setting

J4, J5 A/D Reference Voltage
The A/D converter on the phyCORE-167CR/167CS requires an upper
and lower reference voltage connected at pins 37 and 38 (V
AREF
,
V
AGND
). The reference voltage source can be selected using Jumpers
J4 and J5.

1
:
The second CAN interface is only available with Infineon’s C167CS controller (refer to the
microcontroller User‘s Manual and Data Sheet for further information).
2
:
The feature of rerouting CAN signals to port P8 is only available with Infineon’s C167CS
controller.
3
:
These pins are solely connected to GND of the Development Board when using the phyCORE
module on a phyCORE Development Board HD200. It is not possible to attach an external
GND potential in this configuration.
