8.6 Detailed Error Reports
The detailed error report can be read out after global error mode has been run. On the falling edge of LD, the detailed error report of the selected
test is latched into the shift register and can be clocked out with n *8 clock cycles ( n is the number of AS1109s in a chain) via pin SDO. At the
same time new data can be written into the shift register, which will load on the next rising edge of pin LD. This data will show at the output
drivers, at the falling edge of OEN.
8.6.1
Detailed Temperature Warning Report
The detailed temperature warning report can be read out immediately after global error mode has been run. Bit0 of the 8bit data word represents
the temperature flag of the chip.

Detailed Temperature Warning Report Example
Consider a case where five AS1109s are cascaded in one chain. The detailed error report lists the temperatures for each device in the chain:
IC1:[70°] IC2:[85°] IC3:[66°] IC4:[160°] IC5:[76°]
In this case, IC4 is overheated and will generate a global error, and therefore 5*8 clock cycles are needed to write out the detailed temperature
warning report, and optionally read in new data. The detailed temperature warning report would look like this:
XXXXXXX1 XXXXXXX1 XXXXXXX1 XXXXXXX0 XXXXXXX1
The 0 in the detailed temperature warning report indicates that IC4 is the device with the over-temperature condition.
Note: In an actual report there are no spaces in the output.
