Architectural Overview
• User-enabled stalling when the controller asserts CPU Halt flag during debug
• ADC event trigger
– 16-bit Input Capture modes
• Input edge count capture
• Input edge time capture
– 16-bit PWM mode
• Simple PWM mode with software-programmable output inversion of the PWM signal
■ ARM FiRM-compliant Watchdog Timer
– 32-bit down counter with a programmable load register
– Separate watchdog clock with an enable
– Programmable interrupt generation logic with interrupt masking
– Lock register protection from runaway software
– Reset generation logic with an enable/disable
– User-enabled stalling when the controller asserts the CPU Halt flag during debug
■ ADC
– Four analog input channels
– Single-ended and differential-input configurations
– On-chip internal temperature sensor
– Sample rate of 500 thousand samples/second
– Flexible, configurable analog-to-digital conversion
– Four programmable sample conversion sequences from one to eight entries long, with
corresponding conversion result FIFOs
– Flexible trigger control
• Controller (software)
• Timers
• Analog Comparators
• PWM
• GPIO
– Hardware averaging of up to 64 samples for improved accuracy
