CC3220MOD
SWRS206 â MARCH 2017
⢠Support for a wide range of card clock frequency with odd and even clock ratio
⢠Maximum frequency supported is 24 MHz
5.14.3.10 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:
â 16- or 32-bit programmable one-shot timer
â 16- or 32-bit programmable periodic timer
â 16-bit general-purpose timer with an 8-bit prescaler
â 16-bit input-edge count- or time-capture modes with an 8-bit prescaler
â 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 PWM 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):
â Dedicated channel for each timer
â Burst request generated on timer interrupt
⢠Runs from system clock (80 MHz)
