RM0477: PLLxFRACEN inconsistently named PLL2FRACLEN

[yani-again]

I was learning about how the PLLs work on the H7RS boards, and I discovered a small inconsistency in the RCC_PLLCFGR register.

 

On page 440 and 442 of the RM0477, PLL2FRACEN is incorrectly written down as PLL2FRACLEN (including the ‘L’ near the end).

 

I’ve confirmed that this is incorrect by looking at the HAL and seeing it’s consistently defined as PLL2FRACEN in code (without the ‘L’) inside of stm32h7s3xx.h. Searching for the version with the ‘L’ returned no results, so I’ve concluded that this must be a typo in the reference manual.

 

Could you confirm this is a documentation typo?
