2.2.5 Security and integrity modulesThe following security and integrity modules are available on this device:Table 2-6. Security and integrity modulesModule DescriptionWindowed COP watchdog (WCOP) The COP watchdog is used to force a system reset when the application softwarefails to execute as expected.Cyclic Redundancy Check (CRC) The cyclic redundancy check (CRC) module generates 16/32-bit CRC code forerror detection.2.2.6 Analog modulesThe following analog modules are available on this device:Table 2-7. Analog modulesModule DescriptionAnalog-to-digital converters (ADC) 12-bit successive-approximation ADC module.Comparator (CMP) One comparator that compares two analog input voltages across the full range ofthe supply voltage and can trigger an ADC acquisition, TPM update, or CPUinterrupt.6-bit digital-to-analog converters (DAC) 64-tap resistor ladder network which provides a selectable voltage reference forcomparator.Gate Drive Unit (GDU) • 5 V voltage regulator referenced to VDD for HS pre-drivers• Supports wide operation voltages from 4.5 V to 18 V• Overvoltage detection on the system supply VBUS pin• 1/8 VDD drive to ADC2.2.7 Timer modulesThe following timer modules are available on this device:Table 2-8.
