Hi Support,
working with TM4C123x parts, it seems to me that prescaler values greater than 255 are not accepted, despite the comment.
In this case the functionality of 32/64 bit timer may be limited.
Can you kindly provide me a feedback on this?
//! \param ui32Base is the base address of the timer module.
//! \param ui32Timer specifies the timer(s) to adjust; must be one of
//! \b TIMER_A, \b TIMER_B, or \b TIMER_BOTH.
//! \param ui32Value is the timer prescale value which must be between 0 and
//! 255 (inclusive) for 16/32-bit timers and between 0 and 65535 (inclusive)
//! for 32/64-bit timers.
//!
//! This function configures the value of the input clock prescaler. The
//! prescaler is only operational when in half-width mode and is used to extend
//! the range of the half-width timer modes. The prescaler provides the least
//! significant bits when counting down in periodic and one-shot modes; in all
//! other modes, the prescaler provides the most significant bits.
//!
//! \note The availability of the prescaler varies with the Tiva part and
//! timer mode in use. Please consult the datasheet for the part you are using
//! to determine whether this support is available.
//!
//! \return None.

ASSERT((ui32Timer == TIMER_A) || (ui32Timer == TIMER_B) ||

Thanks and regards,
