H7: CRCDATAR vs CRDATAR1 vs CRCDATAR2

Posted on September 23, 2017 at 14:10

Hello,

rm0433 rev 3 and stm32h742xx.h header are not consistant about CRCDATARx.

From the description in rm0433 3.3.6, is seem that there are CRDATAR1 and CRCDATAR2.

rm0433 3.5 only lists CRCDATAR at offset 0x5c and 0x15c, impying both registers are aliased.

FLASH_TypeDef in stm32h743xx.h lists CRCDATA and CRCDATA2.

Please clarify.
