Reset
The reset pin (PORST#) of the XMC4200 is a bi-directional pin in open drain mode. An internal pull-up resistor
keeps the PORST# pin high during normal operation. A low level at this pin will force a hardware reset. In case of
a MCU internal reset the PORST# pin will drive a low signal.
A reset signal can be issued by
the on-board Reset Button (
“RESET”)
the on-board debug probe (IC101.47)
the external debugger connected to the 10-pin Cortex
™ Debug probe connector (X102)
the Arduino Power Header (X302.3
, “RESET#”)
the pin header X1 (X1.
2, “RESET#”)
An XMC™ internal circuit always ensures a save Power-on-Reset. XMC™ does not require any additional external
components to generate a reset signal during power-up.

CAN Transceiver
The XMC4200 Platform2Go provides a CAN interface via X3, a D-Sub DE-9, and the X1 and X2 connector.
Infineon’s high speed CAN transceiver (IFX1051LE) for industrial applications supports 3.3V I/O logic and is
suitable for 12 V and 24 V bus systems with an excellent EMC performance. The CAN bus (signals CANH, CANL)
are terminated by a 120 Ohm resistor and can provide 5V if R_opt is assembled with a 0 Ohm 0805 resistor (not
assembled by default). The other CAN bus (CAN_TX, CAN_RX) is not terminated by a 120 Ohm and needs to be
terminated externally. To use the CAN_TX/RX pins otherwise see also Table 3.
