RST_A
Internal Reset This terminal is the bidirectional reset terminal of the analog die.
Analog 12
IRQ_A
Internal Interrupt
Output
This terminal is the interrupt output terminal of the analog die indicating
errors or wake-up events.
Analog 13 LIN LIN Bus This terminal represents the single-wire bus transmitter and receiver.
Analog 14 A0CST Analog Input Trim
Terminal
This is the Analog Input Trim Terminal for the A0 input. This is to
connect a known fixed resistor value to trim the current source
measurement.
