4.3.6. Register 0x0C .. 0x0E Sensor Time

The 24Bit sensor time is split and stored in three consecutive registers

•

0x0C

“SENSORTIME_0”

•

0x0D

“SENSORTIME_1”

•

0x0E

“SENSORTIME_2”

Description

Bit 0

por_detected

‘1’ after device power up or softreset. Clear-on-read

4.3.8. Register 0x11 “INT_STATUS”

The “INT_STATUS” register shows interrupt status and is cleared after reading.

data ready interrupt

4.3.9. Register 0x12 .. 0x13 “FIFO_LENGTH”

The FIFO byte counter indicates the current fill level of the FIFO buffer. Its size is 9 bit for 512 bytes and therefore split in two

registers “FIFO_LENGTH_0” and “FIFO_LENGTH_1”.
