On the next falling edge of OEN, current is reduced to I
ately increase to normal levels and the detailed error report can be read out entering error-detection mode.

Shutdown Mode
The AS1110 features a shutdown mode which can be entered via 4 clock pulses during error-detection mode. To
enable the shutdown mode a 0 must be placed at SDI after the rising edge of the 3rd clock pulse.
To disable shutdown mode a 1 must be placed at SDI after the 3rd clock pulse. The shutdown/wakeup information will
be latched through if multiple AS1110 devices are in a chain. At the rising edge of the 4th clock pulse the shutdown bit
will be read out and the AS1110 will shutdown or wakeup.
Note: In shutdown mode the supply current drops down to <10µA.
