Function
General Purpose Digital Input/Output 4 is a Multi-Function Pin. By default and after Power-On-
Reset, this pin is configured as an input. The pin has an internal weak pull-up resistor and if not
being used it can be left unconnected. This multi-function pin can be configured in one of 2
states, namely:
Nominal 2.6V output from the on-chip regulator
Crystal Oscillator Output. If an external Crystal is not being used, this pin can be left
unconnected.
Crystal Oscillator Input. If an external Crystal is not being used, this pin should be connected to
the DGND system ground.
High Voltage Wake-Up pin. This high voltage I/O pin has an internal 10 kΩ pull-down resistor
and a high-side driver to VDD. If this pin is not being used, it should not be connected
externally.
Battery Power Supply to on-chip regulator
Ground Reference for the internal Voltage Regulators
Serial Test Interface Output Pin. If this pin is not being used it should be connected externally
to the IO_VSS ground reference
Ground Reference for High Voltage I/O Pins
LIN Serial Interface Input/Output Pin
General Purpose Digital I/O 4
Output a 2.56MHz clock
