(1) I = Input; O = Output; OD = Open drain
(2) 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 column 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 good functioning of the TPS65950.
(3) The VPRECH, VBATS, and VCCS signals must be connected to each other and with the CPRECH capacitor to GND (see ^{Section 8.2.3},
Configuration with BCI Not Used).
(4) Signal not functional indicates that no signal is presented on the pad after a release reset.
