General-Purpose Timers
Programmable timers can be used to count or time external events that drive the Timer input pins.
The Stellaris
Timer 2, and Timer 3). 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.
Note:
The General-Purpose Timer Module is one timing resource available on the Stellaris
Other timer resources include the System Timer (SysTick) (see “System Timer (SysTick)” on page 40)
and the PWM timer in the PWM module (see “PWM Timer” on page 458).

Timer2 is an internal timer and can only be used to generate internal interrupts or trigger
ADC events.
