NXP Semiconductors KL25 Series - Modes of Operation; External Signal Description; KL25 Sub-Family Reference Manual, Rev. 3, September

• Individual pull control fields with pullup, pulldown, and pull-disablesupport on
selected pins
• Individual drive strength field supporting high and low drive strength on selected
pins
• Individual slew rate field supporting fast and slow slew rates on selected pins
• Individual input passive filter field supporting enable and disable of the
individual input passive filter on selected pins
• Individual mux control field supporting analog or pin disabled, GPIO, and up to
six chip-specific digital functions
• Pad configuration fields are functional in all digital Pin Muxing modes
11.2.2 Modes of operation
11.2.2.1 Run mode
In Run mode, the PORT operates normally.
11.2.2.2 Wait mode
In Wait mode, PORT continues to operate normally and may be configured to exit the
Low-Power mode if an enabled interrupt is detected. DMA requests are still generated
during the Wait mode, but do not cause an exit from the Low-Power mode.
11.2.2.3 Stop mode
In Stop mode, the PORT can be configured to exit the Low-Power mode via an
asynchronous wakeup signal if an enabled interrupt is detected.
11.2.2.4 Debug mode
In Debug mode, PORT operates normally.
11.3 External signal description
The following table describes the PORT external signal.
