8.6 Detailed Error Reports
The detailed error report can be read out after global error mode has been run. At 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 *16 clock cycles ( n is the number of AS1110s in a chain) via pin SDO. At the
same time new data can be written into the shift register, which is loaded on the next rising edge of pin LD. This pattern is shown 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. SDI must be 1 for the first device.
Bit0 of the 16bit data word represents the temperature flag of the chip.

Detailed Temperature Warning Report Example
Consider a case where four AS1110s are cascaded in one chain. The detailed error report lists the temperatures for each device in the chain:
IC1:[70°] IC2:[85°] IC3:[170°] IC4:[60°]
In this case, IC3 is overheated and will generate a global error, and therefore 4*16 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:
XXXXXXXXXXXXXXX1 XXXXXXXXXXXXXXX1 XXXXXXXXXXXXXXX0 XXXXXXXXXXXXXXX1
The 0 in the detailed temperature warning report indicates that IC3 is the device with the over-temperature condition.
Note: In an actual report there are no spaces in the output.
