Fault Output
Write Protection Registers
The ADC Controller internal fault output is directly connected to PWM fault input. Fault output
may be asserted according to the configuration of ADC_EMR (Extended Mode Register) and
ADC_CWR (Compare Window Register) and converted values. This fault line can be enabled or
disabled within PWM.
In case it is activated and asserted by ADC Controller the PWM outputs will be immediately
placed in a safe state (pure combinational path).
To prevent any single software error that may corrupt ADC behavior, certain address spaces
can be write-protected by setting the WPEN bit in the
(ADC_WPMR).
If a write access to the protected registers is detected, then the WPVS flag in the ADC Write Pro-
tect Status Register (ADC_WPSR) is set and the field WPVSRC indicates in which register the
write access has been attempted.
The WPVS flag is reset by writing the ADC Write Protect Mode Register (ADC_WPMR) with the
appropriate access key, WPKEY.
The protected registers are:
