LM3S610 Data Sheet
9 General-Purpose Timers
Programmable timers can be used to count or time external events that drive the Timer input pins.
The LM3S610 controller General-Purpose Timer Module (GPTM) contains three GPTM blocks
(Timer0, Timer1, and Timer 2). 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).
Timers can also be used to trigger analog-to-digital (ADC) conversions. The trigger signals from all
of the general-purpose timers are ORed together before reaching the ADC module, so only one
timer should be used to trigger ADC events.
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
