Architectural Overview
â General-Purpose Timers
â Three General-Purpose Timer Modules (GPTM), each of which provides two 16-bit
timers/counters. Each GPTM can be configured to operate independently:
⢠As a single 32-bit timer
⢠As one 32-bit Real-Time Clock (RTC) to event capture
⢠For Pulse Width Modulation (PWM)
⢠To trigger analog-to-digital conversions
â 32-bit Timer modes
⢠Programmable one-shot timer
⢠Programmable periodic timer
⢠Real-Time Clock when using an external 32.768-KHz clock as the input
⢠User-enabled stalling when the controller asserts CPU Halt flag during debug
⢠ADC event trigger
â 16-bit Timer modes
⢠General-purpose timer function with an 8-bit prescaler (for one-shot and periodic modes
only)
⢠Programmable one-shot timer
⢠Programmable periodic timer
⢠User-enabled stalling when the controller asserts CPU Halt flag during debug
⢠ADC event trigger
â 16-bit Input Capture modes
⢠Input edge count capture
⢠Input edge time capture
â 16-bit PWM mode
⢠Simple PWM mode with software-programmable output inversion of the PWM signal
â ARM FiRM-compliant Watchdog Timer
â 32-bit down counter with a programmable load register
â Separate watchdog clock with an enable
â Programmable interrupt generation logic with interrupt masking
â Lock register protection from runaway software
