Programmers guide

The Device status bits must be read and cleared to be able to read subsequent changes in

the status. The device status bits will remain at “Complete” [1:1] until cleared. It is

recommended that both status bits be cleared to avoid confusion as to the status of the

device.

While in Emergency Override mode the status bits will be automatically cleared whenever

there is a write to CR01H.

VDDUV

The VDDUV bit will be set when the L99UDL01 VDD falls below the under voltage

threshold, VDDUV. It will only be cleared by a read and clear. This bit affects the FE2 bit in

the Global Status byte.
