Function
Port B 2 I/O line (PCINT10/OC1AV/USCK/SCL)
Port B 1 I/O line (PCINT9/OC1BU/DO)
Port B 0 I/O line (PCINT8/OC1AU/DI/SDA)
Port A 0 I/O line (PCINT0/ADC0/RXD/RXLIN)
Port A 1 I/O line (PCINT1/ADC1/TXD/TXLIN)
Port A 2 I/O line (PCINT2/ADC2/OC0A/DO/MISO)
Receive data output
Battery related output for controlling an external voltage regulator
Transmit data input; active low output (strong pull down) after a local wake up request
Output undervoltage and watchdog reset (open drain)
External resistor for adjustable watchdog timing
For factory testing only (tie to ground)
For debug mode: Low watchdog is on; high watchdog is off
Ignition detection (edge sensitive)
5V regulator sense input pin
5V regulator output/driver pin
Battery supply
Enables the device into Normal Mode
Low level watchdog trigger input from microcontroller
High voltage input for local wake-up request; if not needed connect to VS
System Ground LIN-SBC
LIN bus line input/output
