Bit 9
INTRDG: Read/write – used to enable the sensor interleave mode. ADC_ON (bit
4) is always set when enabled, and alternate pressure and temperature ADC
values are used to generate the updated pressure and temperature readings.
0b0
Disabled
0b1
Enabled
Bit 8
AUTO: Read/write – used to enable the sensor auto-update mode. When
enabled pressure and temperature readings are updated automatically at a
rate determined by the value of the DELAY register (address 85).
0b0
Disabled
0b1
Enabled
Bit 7–6
Reserved, read as 0
Bit 5
WRITE: Write only – used to transfer the current values of the configuration
data registers to non-volatile memory when WENB (bit 3) is set.
0b0
No action
0b1

Bit 4
ADC_ON: Read only – indicates when the sensor ADC and bridge are active.
0b0
Inactive
0b1
Active
Bit 3
WENB: Read only – indicates the write status of the configuration data
resisters. It is set and cleared by writing to the ACCESS register (address 5).
0b0
Not writable
0b1
Writable
Bit 2–1
VALID[1..0]: Read only – used to indicate the status of the current values held
in the COMP_PRES and COMP_TEMP registers (addresses 1 and 2).
Automatically cleared by reading the COMP_PRES, COMP_TEMP, ADC_PRES,
ADC_TEMP, MVOLT_PRES or MVOLT_TEMP register (addresses 1, 2, 3, 4, 6 and 7
respectively) whilst the sensor is in the auto-update mode.
0b00
Error – invalid pressure and temperature ADC values detected
0b01
Error – invalid temperature ADC value detected
0b10
Error – invalid pressure ADC value detected
0b11
Data valid
Bit 0
CONV: Read/write – used to trigger an update of the COMP_PRES and
COMP_TEMP registers (addresses 1 and 2) and to indicate when the registers
have been updated. Cleared by writing 0b0, using CLRQERR (bit 13) or by
reading the COMP_PRES, COMP_TEMP, ADC_PRES, ADC_TEMP, MVOLT_PRES or
MVOLT_TEMP register (addresses 1, 2, 3, 4, 6 and 7 respectively) whilst the
sensor is in the auto-update mode.
0b0
Read = data not updated / Write = clear bit
0b1
Read = data updated / Write = request update
