Start-up Sequence
During the start-up sequence the reset or wake-up source will analyzed as well as the diag-
nostics pins (DG1..3) of the ATA6833/ATA6834. When “LIN” is shown as wake-up source,
then power cycling or a wake-up signal on the LIN bus can be the source. “EN2” means that
the Wake-up Button on the Basis board was pressed to wake up the system. The DG3 pin of
the ATA6833/ATA6834 signals temperature warning. When this pin is high, the temperature
warning will be shown on the display. When this pin is low, temperature will signed as okay.
The DG2 pins signal voltage failures like undervoltage, overvoltage, or a charge pump failure.
In these cases, the voltage failure message will be shown. Otherwise, the internal VCC volt-
age of the microcontroller (VCC = 3.3V or VCC = 5.0V) is detected and is visible on the
display. Due to the 16 MHz, the AVR and the integrated hall sensors can only operate at mini-
mum VCC voltage of 4.5V. When VCC is 3.3V, the operation is stopped with the screen as
shown in
