Modes Of Operation - NXP Semiconductors MKL27Z128VFM4 Reference Manual

Table of Contents

• Asynchronous wake-up in low-power modes

• Pin interrupt is functional in all digital pin muxing modes

• Port control

• Individual pull control fields with pullup, pulldown, and pull-disable support on

selected pins

• Individual drive strength field supporting high and low drive strength on selected

• 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

chip-specific digital functions

• Pad configuration fields are functional in all digital pin muxing modes.

11.4.2 Modes of operation

11.4.2.1 Run mode

In Run mode, the PORT operates normally.

11.4.2.2 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.

11.4.2.3 Stop mode

In Stop mode, the PORT can be configured to exit the Low-Power mode via an

asynchronous wake-up signal if an enabled interrupt is detected.

11.4.2.4 Debug mode

In Debug mode, PORT operates normally.
