Datasheet - A p p l i c a t i o n I n f o r m a t i o n
The last pattern written into the shift register will be saved before starting low-current diagnosis mode and can be displayed immediately after the
test has been performed.
Low-current diagnostic mode is started with 3 clock pulses during error detection mode. Then OEN should be enabled for ≥ 2μs for testing. With
the rising edge of OEN the LED test is stopped, and while LD is high the desired error mode can be selected with the corresponding clock
pulses. After LD and OEN go low again the previously saved pattern can be displayed at the outputs.
With the next data input the detailed error code will be clocked out at pin SDO.
Note: See Figure 21 for use of an external test pattern.

9.2 Cascading Devices
To cascade multiple AS1110 devices, pin SDO must be connected to pin SDI of the next AS1110 (see Figure 22) . At each rising edge of CLK the
LSB of the shift register will be written into the shift register SDI of the next AS1110 in the chain.
Note: When n *AS1110 devices are in one chain, n *16 clock pulses are needed to latch-in the input data.
