ATA6621/22/24 Development Board
For testing purposes two jumpers (JP1 and JP2) have been added to the LIN part of this appli-
cation in order to have the opportunity to easily change some parameters at the pins NRES
and VCC/PVCC. Additionally, the switch S1 has been included to generate a wake pulse.
For the microcontroller part of this slave node, only a few blocking capacitors are necessary.
XISP1 is the programming interface and D1, D2, R1 and R2 report the internal status of the
slave node. Because the flasher runs with 12V DC, the transistor T1 is needed to transfer the
5V from the microcontroller to the 12V level. Furthermore, the flasher produces some glitches,
so that there are some capacitors needed in order to block the 12V power supply.
