LM3S3748 Datasheet, PDF (28/753 Pages) List of Unclassifed Manufacturers – Microcontroller

Architectural Overview
• RAM striping
• Peripheral bus segmentation
– Data sizes of 8, 16, and 32 bits
– Source and destination address increment size of byte, half-word, word, or no increment
– Maskable device requests
– Optional software initiated requests for any channel
– Interrupt on transfer completion, with a separate interrupt per channel
■ General-Purpose Timers
– Four General-Purpose Timer Modules (GPTM), each of which provides two 16-bit timers.
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
– 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 in periodic and one-shot mode when the controller asserts the CPU
Halt flag during debug
• ADC event trigger
– 16-bit Timer modes
• General-purpose timer function with an 8-bit prescaler
• Programmable one-shot timer
• Programmable periodic timer
• 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
