LM3S6110 Datasheet, PDF (32/610 Pages) Texas Instruments – Stellaris® LM3S6110 Microcontroller

Architectural Overview
– 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)
– 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
– 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
– 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
■ UART
– Fully programmable 16C550-type UART with IrDA support
