1.7.2.8
PT[3:0] are general-purpose input or output signals. They can have a pull-up or pull-down device selected
and enabled on per signal basis. Out of reset the pull devices are disabled.
1.7.2.9
PL[3:0] are high voltage input ports. The signals can be configured on per signal basis as interrupt inputs
with wake-up capability (KWL[3:0]).
1.7.2.10
This pad is connected to the single-wire LIN data bus.
1.7.2.11
Outputs of the two high-side drivers intended to drive incandescent bulbs or LEDs.
1.7.2.12
Outputs of the two low-side drivers intended to drive inductive loads (relays).
1.7.2.13
This pin can be connected to the supply (Battery) line for voltage measurements. The voltage present at
this input is scaled down by an internal voltage divider, and can be routed to the internal ADC via an analog
multiplexer. The pin itself is protected against reverse battery connections. To protect the pin from external
fast transients an external resistor is needed.
1.7.2.14
AN[5:0] are the analog inputs of the Analog-to-Digital Converter.
1.7.2.15
1.7.2.15.1
This signal is associated with the slave select SS functionality of the serial peripheral interface SPI.
1.7.2.15.2
This signal is associated with the serial clock SCK functionality of the serial peripheral interface SPI.
1.7.2.15.3
This signal is associated with the MISO functionality of the serial peripheral interface SPI. This signal acts
as master input during master mode or as slave output during slave mode.
