General-Purpose Timers
Programmable timers can be used to count or time external events that drive the Timer input pins.
The LM3S102 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:
–
–
–
–
16-bit Timer modes:
–
–
–
–
16-bit Input Capture modes:
–
–
16-bit PWM mode:
–
Programmable one-shot timer
