Table 41. DEVSTAT3 - device status register (address 04h) bit description

Bit

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

OSCTRAIN_ERR

The oscillator training error bit is set if an error detected in either the oscillator training

settings, or the master communication timing. Once the error condition is corrected, the

OSCTRAIN_ERR bit is cleared after a read of the OSCTRAIN_ERR bit through any

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

communication interface.

0 — No error detected

1 — Oscillator training error

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 101.

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

Section 10 "Static characteristics ".
