LM3S101 Data Sheet
9 General-Purpose Timers
Programmable timers can be used to count or time external events that drive the Timer input pins.
The LM3S101 controller General-Purpose Timer Module (GPTM) contains two GPTM blocks
(Timer0 and Timer1). Each GPTM block provides two 16-bit timer/counters (referred to as TimerA
and TimerB) that can be configured to operate independently as timers or event counters, or
configured to operate as one 32-bit timer or one 32-bit Real-Time Clock (RTC).
The following modes are supported:
„ 32-bit Timer modes:
– Programmable one-shot timer
– Programmable periodic timer
– Real-Time Clock using 32.768-KHz input clock
– Software-controlled event stalling (excluding RTC mode)
„ 16-bit Timer modes:
– General-purpose timer function with an 8-bit prescaler
– Programmable one-shot timer
– Programmable periodic timer
– Software-controlled event stalling
„ 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
