3.4 Supported MCU-Link features
MCU-Link includes several mandatory and optional features. Table 20 summarizes the MCU-Link features
supported on the KW45B41Z-EVK board.
Feature Description
Serial wire debug (SWD) / serial wire debug
trace output (SWO)
Allows SWD-based debugging with SWO for profiling and/or low
overhead debug standard I/O communication
Virtual communication (VCOM) serial port Adds a serial COM port on the host computer, and connects it to the
target MCU by using MCU-Link as a USB-to-UART bridge
USB serial input/output (USBSIO
[1]
Adds a USB serial I/O port on the host computer, and connects it to the
target MCU by using MCU-Link as a USB-to-SPI bridge or USB-to-I2C
bridge
External debug probe support Allows debugging the target MCU (KW45B41Z) using an external debug
probe, instead of MCU-Link. Support for external debug probe is enabled
by disabling SWD feature. While using external debug probe, VCOM and
USBSIO features can be used.
External target support
[1]
Allows debugging an external target MCU using MCU-Link
Energy/power/current/voltage consumption
measurement
[1]
(MCUXpresso IDE only)
Allows onboard measurement of current drawn by the target MCU

[1] J-Link firmware does not support this feature.)
3.5 Supported debug scenarios
In the KW45B41Z-EVK board, the MCU-Link debug probe target can be either the KW45B41Z MCU or an
external target compliant with MCU-Link. The board also allows you to use an external debugger for debugging
the KW45B41Z MCU, in place of the MCU-Link debug probe.
Table 21 describes the debug scenarios supported on the KW45B41Z-EVK board.
Debug scenario Feature support
Use MCU-Link as debugger for the target MCU
(KW45B41Z)
• Serial wire debug (SWD):
– MCU-Link SWD feature is enabled (MCU-Link SWD disable jumper
JP22 is open)
– The target MCU SWD interface is connected to MCU-Link
– The target MCU SWD connector J16 is not used for external
connection
• Virtual communication (VCOM): MCU-Link VCOM feature is enabled
• USB serial input/output (USBSIO): MCU-Link USBSIO feature is
enabled
• Target selection: Target selection jumper JP26 is open
• Target power selection: Target power selection jumper JP28 is set to
1-2 shorted
Use an external debugger to debug the target
MCU (KW45B41Z)
• SWD:
– Disable MCU-Link SWD feature by shorting MCU-Link SWD disable
jumper JP22
