ADIN5
used to read out the battery pack thermistor. The thermistor must be biased with an external pull-up to a voltage rail greater than
the ADC input range. In order to save current when the thermistor reading is not required, it can be biased from one of the general
purpose IOs such as GPO1. A resistor divider network should assure the resulting voltage falls within the ADC input range, in
particular when the thermistor check function is used.

on channel 7. This input is muxed on the GPO4 pin. In the application, a second ambient light sensor is supposed to be connected
here.
TSX1 AND TSX2, TSY1 AND TSY2 -
is connected to Y1 and Y2. In inactive mode, these pins can also be used as general purpose ADC inputs. They are respectively
mapped on ADC channels 4, 5, 6, and 7. In interrupt mode, a voltage is applied to the X-plate (TSX2) via a weak current source
to VCORE, while the Y-plate is connected to ground (TSY1).

When SWBST is configured to supply the UVBUS pin in OTG mode, the feedback will switch to sense the UVBUS pin instead
This is the regulator used to provide a voltage to an external USB transceiver IC.
