The ATA6612/ATA6613-EK has three port connectors for the microcontroller ports PortB,
PortC and PortD. All non-reserved I/O-pins available from the microcontroller are routed to the
corresponding connectors to give the user easy access to them. All three connectors provide,
besides the port pins, a voltage supply pin (5V from the internal voltage regulator) and a
ground pin in order to easily connect application-specific add-ons.
The pinouts of the three connectors are shown in
In order to be more flexible and to meet as many requirements as possible, some jumpers are
provided on the development board. With the help of these jumpers, users have the opportu-
nity to engage with the system itself in order to test some features and/or to adapt the system
to their requirements. In the following sections all jumpers on the development board are
briefly described. For additional information, check the previous sections.
By default, this jumper is set to generate a connection between the NRES output of the LIN
SBC and the reset input of the microcontroller. This results in a resetting of the microcontroller
in the event of watchdog failures or undervoltage at the voltage regulator output. As described
earlier in this document, there may be some cases when it is helpful to remove this jumper
(e.g., testing purposes, debugging). However, for normal operation of the LIN node, this
jumper should be set.
