Function

IO (WKUP0/1)

General Purpose Backup Register

(GPBR)

Security / Immediate GPBR clear (asynchronous) on

Tamper detection through WKUP0/1 IO pins.

Power Management Controller

(PMC)

PMC

Safety / Automatic switch to reliable main RC oscillator

in case of main crystal clock failure

PMC

Pulse Width Modulation(PWM)

Safety / Puts the PWM outputs in safe mode (main

crystal clock failure detection)

Analog Comparator Controller

(ACC)

PWM

Safety / Puts the PWM outputs in safe mode

(overcurrent sensor, etc.)

Analog-to-Digital Converter (ADC)

PWM

Safety / Puts the PWM outputs in safe mode

(overspeed,overcurrent detection, etc.)

Timer Counter (TC)

PWM

Safety / Puts the PWM outputs in safe mode (overspeed

detection through timer quadrature decoder)

PWM

Safety / Puts the PWM outputs in safe mode (general

purpose fault inputs)

Parallel Capture (PC)

PC is embedded in PIO (capture image from sensor

directly to system memory)

IO (ADTRG)
