KW45B41Z-EVK Board User Manual
Part identifier PCB label Button name Description
hold down this button while pressing and releasing the
reset button, or while connecting power to the board.
If an application in the target MCU internal flash is
crashing or disabling the SWD port unintentionally,
then ISP mode can be useful to recover control of the
board. See KW45B41Z Reference Manual for more
information on ISP mode.
By default, SW4 is disabled. It can be enabled by
shorting jumper JP25.
SW5 SW_WAKE_UP Wake-Up button Wakes up the target MCU (KW45B41Z) from Deep
Power-Down mode

Table 7 describes the KW45B41Z-EVK light-emitting diodes (LEDs) that correspond to the target MCU. The
board also has some MCU-Link specific LEDs, which are described in Section 3.9. The LEDs are shown in
Figure 2.
