Figure 30. NMI pin biasing
• Debug interface
This MCU uses the standard Arm SWD interface protocol as shown in the
following figure. While pull-up or pull-down resistors are not required
(SWD_DIO has an internal pull-up and SWD_CLK has an internal pull-down),
external 10 kΩ pull resistors are recommended for system robustness. The
RESET_b pin recommendations mentioned above must also be considered.

Figure 31. SWD debug interface
• Low leakage stop mode wakeup
Select low leakage wakeup pins (LLWU_Px) to wake the MCU from one of the
low leakage stop modes (LLS/VLLSx). See K32 L2A Signal Multiplexing and
Pin Assignments chapter for pin selection.
• Unused pin
Unused GPIO pins must be left floating (no electrical connections) with the MUX
field of the pin’s PORTx_PCRn register equal to 000. This disables the digital
input path to the MCU.
