Latch Bits:
Nonvolatile State
Power Loss
The states of the latch bits (LT01–LT32) are retained if power to the device is
lost and then restored. If a latch bit is asserted (for example, LT02 := logical 1)
when power is lost, it is asserted (LT02 := logical 1) when power is restored. If
a latch bit is deasserted (for example, LT03 := logical 0) when power is lost, it
is deasserted (LT03 := logical 0) when power is restored.
