Re: Tiva HAL Support
Hi,
Tiva devices are now able to run in Tickless mode.
Note that:
32 bit timers (WGPT) use a 16 bit prescaler so at 80MHz the ST_FREQUENCY must be at least 1250Hz. These are only available in TM4C123x devices.
16 bit timers (GPT) use an 8 bit prescaler so at 80MHz the ST_FREQUENCY must be at least 312500Hz. At 120MHz the ST_FREQUENCY must be at least 468750Hz. I think these are not usable for Tickless mode because of the high minimum frequency.
