Definition
This pin is a special-function, bidirectional I/O port pin that can
is shared with other functional modules in the MCU.
These pins are the reference voltage pins for the analog-to-
digital converter (ADC).
These pins are the power supply pins for the analog-to-digital
converter.
These pins are the ground and power supply pins, respectively.
The MCU operates from a single power supply.
These pins are special-function, bidirectional I/O port pins that
are shared with other functional modules in the MCU.

This pin is the bidirectional reset pin of the analog die.
This pin is the interrupt output pin of the analog die indicating
errors or wake-up events.
This pin is the SPI slave select pin for the analog chip.
This pin represents the single-wire bus transmitter and receiver.
This device includes power MOSFETs configured as four half-
bridge driver outputs. These outputs may be configured for step
motor drivers, DC motor drivers, or as high-side and low-side
switches.
These pins are device power supply pins.
