Phase two: “error detection”
The 16 data bits must be set “1” in order to set ON all the outputs during the detection. The
data are latched by LE/DM1 and after that the outputs are ready for the detection process.
When the micro controller switches the OE\DM2 to LOW, the device drives the LEDs in
order to analyze if an OPEN or SHORT condition has occurred.
Figure 16. Detection diagram
The LEDs status will be detected at least in 1 microsecond and after this time the
microcontroller sets OE\DM2 in HIGH state and the output data detection result will go to
the microprocessor via SDO.
Detection mode and normal mode use both the same format data. As soon as all the
detection data bits are available on the serial line, the device may go back to normal mode
of operation. To re-detect the status the device must go back in normal mode and re-
entering in error detection mode.
