Modes Of Operation; Run Mode; Stop Mode - NXP Semiconductors freescale KV4 Series Reference Manual

Table of Contents

• Selectable clock source for digital input filter with a five bit resolution on filter

• Functional in all digital pin multiplexing modes

• Port control

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

• Individual drive strength field supporting high and low drive strength

• Individual slew rate field supporting fast and slow slew rates

• Individual input passive filter field supporting enable and disable of the

individual input passive filter

• Individual open drain field supporting enable and disable of the individual open

drain output

• 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.

12.2.2 Modes of operation

In Run mode, the PORT operates normally.

12.2.2.2 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.

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.

In Stop mode, the digital input filters are bypassed unless they are configured to run from

the LPO clock source.
