Description
6
PABS_HIGH
The absolute pressure out-of-range high status bit is set if the absolute pressure exceeds the absolute pressure out-
of-range high limit. The PABS_HIGH bit is cleared on a read of the DSP_STAT register through any communication
interface or on a data transmission that includes the error in the status field.

3
PABS_LOW
The absolute pressure out-of-range low status bit is set if the absolute pressure exceeds the absolute pressure out-
of-range low limit. The PABS_LOW bit is cleared on a read of the DSP_STAT register through any communication
interface or on a data transmission that includes the error in the status field.
ST_INCMPLT
The self-test incomplete bit is set after a device reset and is only cleared when one of the analog or digital self-test
modes is enabled in the ST_CTRL register (ST_CTRL[3] = '1' | ST_CTRL[2] = '1' | | ST_CTRL[1] =
'1' | | ST_CTRL[0] = '1').
0 — An analog or digital self-test has been activated since the last reset.
1 — No analog or digital self-test has been activated since the last reset.
2
ST_ACTIVE
The self-test active bit is set if any self-test mode is currently active. The self-test active bit is cleared when no self-test
mode is active.
ST_ACTIVE= ST_CTRL[3] | ST_CTRL[2] | ST_CTRL[1] | ST_CTRL[0]

0
CM_ERROR
ST_ERROR
The absolute pressure common mode error status bit is set if the common mode value of the analog front end exceeds
predetermined limits. The CM_ERROR bit is cleared on a read of the DSP_STAT register through any communication
interface or on a data transmission that includes the error in the status field.
The self-test error flag is set if an internal self-test fails as described in Section 7.3.2. This bit can only be cleared by a
device reset.
7.7.17 DEVSTAT_COPY - device status copy register (address 61h)
The device status copy register is a read-only register that contains a copy of the device
status information contained in the DEVSTAT register. See Section 7.7.2.1 "DEVSTAT
- device status register (address 01h)" for details regarding the DEVSTAT register
contents. A read of the DEVSTAT_COPY register has the same effect as a read of the
DEVSTAT register.

7.7.18 SNSDATA0_L, SNSDATA0_H - sensor data #0 registers (address 62h, 63h)
The sensor data #0 registers are read-only registers that contain the 16-bit sensor
data. See Section 7.3.4.4 "Absolute pressure output data scaling equation" for details
regarding the 16-bit sensor data.
The SNSDATA0_H register value is latched on a read of the SNSDATA0_L register
value until the SNSDATA0_H register is read. To avoid data mismatch, the user is
