0x0e
R/W Name Description Initial Value
R SIGNAL_STRENGTH Received signal strength --
Bit Function
7:0 Received signal strength calculated from the value of the highest peak in the
correlation record and how many acquisitions were performed.
0x0f
R/W Name Description Initial Value
R FULL_DELAY_HIGH Distance measurement high byte --
Bit Function
7:0 Distance measurement result in centimeters, high byte.
0x10
R/W Name Description Initial Value

0x11
R/W Name Description Initial Value
R/W OUTER_LOOP_COUNT Burst measurement count control 0x01
Bit Function
7:0 0x00-0x01: One measurement per distance measurement command.
0x02-0xfe: Repetition count per distance measurement command.
0xff: Indenite repetitions after initial distance measurement command.
See ACQ_CONFIG_REG (0x04) and MEASURE_DELAY (0x45) for non-
default automatic repetition delays.
0x12
R/W Name Description Initial Value
R/W REF_COUNT_VAL Reference acquisition count 0x05
Bit Function
7:0 Non-default number of reference acquisitions during measurement. ACQ_
CONFIG_REG (0x04) bit 2 must be set.
0x14
R/W Name Description Initial Value
R LAST_DELAY_HIGH Previous distance measurement high
byte
--
Bit Function
7:0 Previous distance measurement result in centimeters, high byte.
0x15
R/W Name Description Initial Value
R LAST_DELAY_LOW Previous distance measurement low
byte
--
Bit Function
7:0 Previous distance measurement result in centimeters, low byte.
0x16
R/W Name Description Initial Value
R UNIT_ID_HIGH Serial number high byte Unique
Bit Function
7:0 Unique serial number of device, high byte.
0x17
R/W Name Description Initial Value
R UNIT_ID_LOW Serial number low byte Unique
Bit Function
7:0 Unique serial number of device, high byte.
0x18
R/W Name Description Initial Value
W I2C_ID_HIGH Write serial number high byte for I2C
address unlock
--
Bit Function
7:0 Write the value in UNIT_ID_HIGH (0x16) here as part of enabling a non-
default I2C address. See I2C_ID_LOW (0x19) and I2C_SEC_ADDR (0x1a).
0x19
R/W Name Description Initial Value
W I2C_ID_LOW Write serial number low byte for I2C
address unlock
--
Bit Function
7:0 Write the value in UNIT_ID_LOW (0x17) here as part of enabling a non-default
I2C address. See I2C_ID_HIGH (0x18) and I2C_SEC_ADDR (0x1a).
0x1a
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 7-bit values with a ‘0’ in the least signicant bit (even
hexadecimal numbers).
I2C_ID_HIGH (0x18) and I2C_ID_LOW (0x19) must have the correct value for
the device to respond to the non-default I2C address.
0x1c
R/W Name Description Initial Value
R/W THRESHOLD_
BYPASS
Peak detection threshold bypass 0x00
Bit Function
7:0 0x00: Use default valid measurement detection algorithm based on the peak
value, signal strength, and noise in the correlation record.
0x01-0xff: Set simple threshold for valid measurement detection. Values 0x20-
0x60 generally perform well.
0x1e
R/W Name Description Initial Value
R/W I2C_CONFIG Default address response control 0x00
Bit Function
