4 Connector Pin Assignment
4.4 Infineon DAP Debug Connector (10-pin)
Infineon’s 10-pin Device Access Port Debug Connector (DAP) is a two-wire tool access port for microcontrollers
and similar devices. It allows robust high-speed connections over a long cable for automotive applications. The
pin assignment of the DAP Debug Connector is shown in Table 9. The board comes with a DAP connector. You
can connect a DAP hardware here. If you use this connector, make sure that the miniWiggler JDS is not activ
(LED5 is off). For more information, we refer you to the DAP Connector Manual.

Description
1
VREF
VEXT
O
Supply voltage from the target system. The voltage has to be
strong enough to supply the target side of the level shifters
within the tool hardware up to about 20 MHz DAP operating
frequency. The required supply current is in the range of 5
mA, mainly caused by signal switching. It can be reduced by
lowering frequency and capacitance. Beyond 20 MHz the
tool hardware has to supply the level shifter from another
source and use this pin just as a voltage reference

DAP1
TMS
IO
DAP: Data pin.
SPD
IO
SPD: Data pin.
UART
IO
Single-wire UART. Serial communication interface (e.g. used
for Bootstrap Loader BSL).
3
GND
GND
Recommended pin for signal return of DAP1 for high
frequency impedance matching.
4
DAP0
TCK
I
DAP: Clock.
SUP
I
SPD: Optional user pin value for feedback into the target
system. Otherwise reserved
5
GND
GND
Recommended pin for signal return of DAP0 for high
frequency impedance matching.
6
DAP2
P21.7
IO
DAP: Optional second data pin.
USER0
IO/O
Generic signal that can be used for non specified functions.
7
KEY (GND
in cable)
GND
-
If the recommended connector with keying shroud is not
used, this pin provides another option to enforce
polarization. In that instance this pin is removed from the
target connector and the associated jack in the cable
connector closed with a plastic pin for example.
8
DAP3
/TRST
IO
DAP: Optional third data pin.
USER1
IO/I
Generic signal that can be used for non-specified functions.
(DAPEN)
I
Optional indicator that the tool is connected. This can be
used to enable the DAP interface of the device
9
GND
GND
Supply ground.
10
RESET
/PORST
IO
Target reset signal. Open drain active low signal. May be
used bi-directionally to drive or sense the target reset signal.
Usually driven by the tool to reset the target system. The
target system is responsible for providing a pull-up to VREF
