Hi Afifi,
You mean you want to know the R5F clock frequency running?

Hi Afifi,
We do not have register which provides info on the MCU clock frequency. May I know the reason you asking for this?

Hello Kumar,
I have software configuring the MCU peripheral and need to know the operating frequency.

Hi Afifi,
As I mentioned we do not have a register which provides operating frequency. MCU clock runs at 400MHZ in case of AM263x.

Hello Afifi,
As Sunil mentioned, there is not a register to provide the exact frequency value of the R5FSSx Clock, however, the TOP_RCM.R5SS_CLK_STATUS/TOP_RCM.R5ss_CLK_SRC_SEL registers provide the root clock being used as described in the TRM clocking chapter (screenshots below for reference). By also finding the value of R5Sx_CLK_DIV_SEL, the operating frequency can be determined.
In the default case, DPLL_CORE_HSDIV0_CLKOUT0 (400 MHz) is used with divider value of 1 resulting in a 400 MHz clock source for R5FSSx.
