■ General-Purpose Timers
– Three General-Purpose Timer Modules (GPTM), each of which provides two 16-bit
timer/counters. Each GPTM can be configured to operate independently as timers or event
counters as a single 32-bit timer, as one 32-bit Real-Time Clock (RTC) to event capture, or
for Pulse Width Modulation (PWM)
– 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
– 16-bit Timer modes
•
General-purpose timer function with an 8-bit prescaler
