status

Bit[5]

Power-On status. If set to 1, the part has had a power-up event, either because the part was turned on

or because there was a power-supply voltage disturbance

A value of 1 is the default for the first register read after power-on reset.

Note:

All interrupt threshold settings in the registers have been reset to power-on default states and

should be examined if the Power-On status flag is set. In the event of a power-up event while

in the ALS/UVBS_Raw Mode, this special operation mode is turned off. To restore this mode,

the initialization sequence described in Table 3.3 must be repeated before the mode can be

reactivated.

The flag is cleared after the register is read.

Bit[4]

LS interrupt status (updated even if the interrupt pin is disabled)

interrupt condition has not occurred (default)

interrupt condition has occurred (cleared after read)

Bit[3]

LS data status

old data, already read (default)

new data, not yet read (cleared after read)

Bit[2:0]

Reserved
