Timers

Programmable timers can be used to count or time external events that drive the timer input pins. The CC3220x general-purpose timer module (GPTM) contains 16- or 32-bit GPTM blocks. Each 16- or 32-bit GPTM block provides two 16-bit timers or counters (referred to as Timer A and Timer B) that can be configured to operate independently as timers or event counters, or they can be concatenated to operate as one 32-bit timer. Timers can also be used to trigger µDMA transfers.

The GPTM contains four 16- or 32-bit GPTM blocks with the following functional options:

  • Operating modes:
    • 16- or 32-bit programmable one-shot timer
    • 16- or 32-bit programmable periodic timer
    • 16-bit general-purpose timer with an 8-bit prescaler
    • 16-bit input-edge count- or time-capture modes with an 8-bit prescaler
    • 16-bit PWM mode with an 8-bit prescaler and software-programmable output inversion of the PWM signal
  • Counts up or counts down
  • Sixteen 16- or 32-bit capture compare pins (CCP)
  • User-enabled stalling when the microcontroller asserts CPU Halt flag during debug
  • Ability to determine the elapsed time between the assertion of the timer interrupt and entry into the interrupt service routine
  • Efficient transfers using micro direct memory access controller (µDMA):
    • Dedicated channel for each timer
    • Burst request generated on timer interrupt
  • Runs from system clock (80 MHz)
