If the temperature of a cluster reaches the thermal warning threshold then a dedicated status flag (TW_CLx bit) is
set and an interrupt is issued.
If the temperature of a cluster reaches the thermal shutdown threshold then a dedicated status flag is set, the
outputs assigned to that cluster are shut down and depending on their configuration bit REGFAIL_GO_REC all
outputs are shut down or not as described in the Section 3.6.2.5: Regulator faults management.

Clusters temperature is converted through the ADC and readable by SPI (through TEMP_CLx[9..0] bits), only in
active full-power mode
Note:
•
In the DEEP-SLEEP state all clusters are disabled.
•
In active low power all clusters are disabled except Th_CL0 to detect TSDC.
Monitoring of central thermal cluster is insured by analog comparator, while other thermal clusters are monitored
through the ADC.
Latent fault detection of TSDC thermal comparator is covered by Analog-BIST.
Latent fault detection of digital thermal monitor and ADC handler is covered by a Digital-BIST.
