Bit Function
2
Reference overflow flag
0: Reference data has not overflowed
1: Reference data in correlation record has reached the maximum
value before overflow (this occurs when taking measurements with
biasing enabled)
1
Signal overflow flag
0: Signal data has not overflowed
1: Signal data in correlation record has reached the maximum
value before overflow (this occurs with a strong received signal
strength)
0
Busy flag
0: Device is ready for a new command
1: Device is busy taking a measurement or powering on

R/W Name
Description
Initial Value
R/W I2C_SEC_ADDR Write new I2C address after
unlock
--
Bit Function
7:0 Non-default I2C address.
Available addresses are any non-zero 7-bit values.
The five byte sequence is composed of the four byte UNIT_ID and
the one byte slave address. The UNIT_ID must be entered with the
least significant byte first.
UNIT_ID_0_UNLOCK (
), UNIT_ID_1_UNLOCK
(
), UNIT_ID_2_UNLOCK (
), and
UNIT_ID_3_UNLOCK (
) must have the correct value
for the device to respond to the non-default I2C address.
Example: UNIT_ID = 0x01020304, (LSB = 04, MSB = 01)
Example write starting at 0x16: 0x0403020155, would match on
UNIT_ID and set slave address to 0x55 (The effective 8-bit
secondary I2C address would be 0xAA write and 0xAB read)
NOTE:
You must enable ENABLE_FLASH_STORAGE before
configuring the secondary I2C address (
