Description

U_RW_ERR

When ENDINIT is set, an error detection is enabled for all user writable registers. The

error detection code is continuously calculated on the user writable registers and verified

against a previously calculated error detection code. If a mismatch is detected in the error

detection, the U_RW_ERR bit is set. This error is cleared by a read of the DEVSTAT2

error in the status field.

0 — No error detected

1 — Error detected in the user read/write array

U_W_ACTIVE

The user OTP write in process status bit is set if a user initiated write to OTP is in process.

The U_W_ACTIVE bit is automatically cleared once the write to OTP is complete.

0 — No OTP write in process

1 — OTP write in process

TEMP0_ERR

The temperature error bit is set if an overtemperature or undertemperature condition

exists. This error is cleared by a read of the DEVSTAT2 register through any

communication interface or on a data transmission that includes the error in the status

field.

0 — No error detected

1 — Overtemperature or undertemperature error condition detected

Description

MISO_ERR

In SPI mode, the MISO data mismatch flag is set when a MISO Data mismatch fault

occurs. The MISO_ERROR bit is cleared by a read of the DEVSTAT3 register through any

communication interface, or by a status transmission including the error status through the

SPI.

0 — No error detected

1 — MISO data mismatch

Table 44. DEVSTAT3 - device status register (address 04h) bit description

7.7.3 TEMPERATURE - temperature register (address 0Eh)

The temperature register is a read-only register that provides a temperature value for the

IC. The temperature value is specified in the temperature sensor signal chain section of

Table 104.

Note: The device is only guaranteed to operate within the temperature limits specified in

Section 10 "Static characteristics ".
