Hi,
It says that "LE can be kept high if bit R5[23] is changed to 0 (from its default value of 1). If this bit is changed, then the operation of the part is not ensured because it is not tested under these conditions" in page 19 of datasheet. I want to know what issue is occurred if LE is kept high. Also if LE signal has to be kept low after programming, please let me know how to work the MCU as maximum operation frequency of 20MHz.
Regards,
