Inconsistent reset value of registers FLASHCFGA - FLASHCFGB

Hi,

 

my customer reports different rest value of flash accelerator registers compared to documentation.

 

silicon por value reads as 0x8000423A but documentation UM10503 V2.1 says it should be 0x8000F03A

 

According to documentation the value we read from the chip should be good only up to 107 MHz, but this value actually works up to 180MHz.

 

Documentation suggest value of 0x8000803A for 180 MHz "without touching the three least significant nibbles " that anyway are 0x32A and not as documented 0x03A.

 

The Question is : for 180MHz operation is the silicon reset value ok or not ?

 

Thanks

BR
