ATA6833/ATA6834 Diagnostic Function
Software Module Overview
Sleep Mode:
Decay Mode:
If a voltage failure, temperature warning, or short-circuit detection occurs, a message will be
displayed as long as the voltage failure or temperature warning is present. For the short circuit
detection, the message must be acknowledged by touching the screen.
Figure 8-3.
The software is implemented in C language and the source code can be compiled using com-
pilers from IAR Systems as well as from GCC for AVR.
Figure 8-4.
The software consists of several modules. The modules Graphics, LCD, Touch, ADC and SW
SPI driver are only needed for the user interface. For motor control the following modules are
necessary: Time Base Generator, Motor Control, ATA6833, Timer8, Timer16, PLL and PSC
driver. ALIN remote control function is also implemented.

• This function activates a countdown of 3 seconds. After this, the ATA6833/ATA6834 is set
• Enables a slow decay of the half-bridge control.
into sleep mode. Pressing the wake-up button on the Basis board restarts the
ATA6833/ATA6834.
Note: this button can only be used when the motor is stopped.
