FXPS7115D4

Digital absolute pressure sensor, 40 kPa to 115 kPa

Bit

Symbol

Description

DEVRES

The device reset bit is set following a device reset. This error is cleared by a read of the

DEVSTAT register through any communication interface or on a data transmission that

includes the error in the status field.[2]

0 — Normal operation

1 — Device reset occurred

DEVINIT

The device initialization bit is set following a device reset. The bit is cleared once sensor data

is valid for read through one of the device communication interfaces (tPOR_DataValid).

0 — Normal operation

1 — Device initialization in process

After POR and/or soft reset, see Section 7.5.5 for initialization sequence.

[1]

During POR and soft reset ignore DEVSTAT1 error flags, refer to Section 7.5.5.

[2]

A common timer is used for all error bits in the DEVSTAT1 register. If any supply error is present, the timer is reset to tUVOV_RCV. This bit is cleared based

on the state of the SUP_ERR_DIS bit in the DEVLOCK_WR register as shown in Section 7.7.4.

Description

VCCUV_ERR

The VCC undervoltage error bit is set if the VCC voltage falls below the voltage specified in

Table 104. See Section 7.1 for details on the VCC undervoltage monitor.

0 — No error detected

1 — VCC voltage low

INTREGA_ERR

The internal analog regulator voltage out-of-range error bit is set if the internal analog

regulator voltage falls outside expected limits.

0 — No error detected

1 — Internal analog regulator voltage out of range

INTREG_ERR

The internal digital regulator voltage out-of-range error bit is set if the internal digital regulator

voltage falls outside expected limits.

0 — No error detected

1 — Internal digital regulator voltage out of range

INTREGF_ERR

The internal OTP regulator voltage out-of-range error bit is set if the internal OTP regulator

voltage falls outside expected limits.

0 — No error detected

1 — Internal OTP regulator voltage out of range

CONT_ERR

The continuity monitor passes a low current through a connection around the perimeter of

the device and monitors the continuity of the connection. The error bit is set if a discontinuity

is detected in the connection.
