5.13.5.11 Timers
Programmable timers can be used to count or time external events that drive the timer input pins. The
CC3220MODx 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)
