I am now using TWR-KW24D512 and wants to keep TWR-KW24D512 running under MCG FEI mode after reseting.
I did not change the default register value for MCG_C1 and MCG_C4, and also use the factory's trim value after resetting.
Could I confirm that the board is running under FEI mode?
Could I know what is the rate of the system clock? Is it 32.768kHz?
Could I know UART module clock is the system clock?
I encounter a UART issue after resetting. The UART does not work properly if the UART module clock is 32768*640.
But it begins to work, if the UART module clock is 32768*480....
Could I know the reason?
