Dears.
Now I’m checking out the logic of ECO(16MHz) stabilization time in both SDL and MCAL.
Please review the following questions if anyone has the any idea or tips.
<1>
In case of SDL, After configuration of clock trims then ECO enable is active, it wait for unlimited loop as the following.
|
SRSS->unCLK_ECO_CONFIG.stcField.u1ECO_EN = 1ul;
while(SRSS->unCLK_ECO_STATUS.stcField.u1ECO_OK == 0ul);
while(SRSS->unCLK_ECO_STATUS.stcField.u1ECO_READY == 0ul);

In MCAL, I can find the “ECO Amp statilization timeout” configuration, normally you IFX recommend that it is set bigger than 1,000,000.
I understood that 1,000,000 means “count value” which decresases 1step in each do while loop of source code until ECO is stabilized actually like (regSrssAddrPtr->CLK_ECO_STATUS == MCU_REG_MASK_SRSS_CLK_ECO_STATUS_ECO_OK).
I’am wondering that is possible to convert “1,000,000” count value to real time and If possible, could you tell me how to convert it in time domain ?
<2>
If ECO operation is unstabilized like a high level of tolerance and it affects unusually MCU operation, is there any way to trap the unstable-abnormal ECO condition inside of MCU ?
Thanks and best regards,
Kevin Han.
