(1) This column provides the connection when the associated feature is not used or not connected. When there is a pin muxing, not all
functions on the muxed pin are used. But even if a function is not used, the Default Configuration After Reset Released column still
applies.
Connection criteria:
– Analog pins:
– For input: GND
– For output: Floating (except VPRECH is connected to GND)
– For I/O if input by default: GND (except for audio features input: capacitor to ground with a 100-nF typical value capacitor)
– Digital pins:
– For input: GND (except keypad and STP are left floating)
– For input and pullup: Floating
– For output: Floating
– For I/O and pullup: Floating
N/A (not applicable): When the associated feature is mandatory for correct functioning of the TPS65920/TPS65930 device
(2) The signal VPRECH must be connected to the CPRECH capacitor to GND.
(3) Signal not functional indicates that no signal is presented on the pad after a release reset.
