Function
Security / Immediate GPBR clear (asynchronous) on
Tamper detection through WKUP0/1 IO pins.
Safety / Automatic switch to reliable main RC oscillator
in case of main crystal clock failure
Safety / Puts the PWM outputs in safe mode (main
crystal clock failure detection)
Safety / Puts the PWM outputs in safe mode
(overcurrent sensor, etc.)
Safety / Puts the PWM outputs in safe mode
(overspeed,overcurrent detection, etc.)
Safety / Puts the PWM outputs in safe mode (overspeed
detection through timer quadrature decoder)
Safety / Puts the PWM outputs in safe mode (general
purpose fault inputs)
PC is embedded in PIO (capture image from sensor
directly to system memory)
