Error in PM0214 Programming manual with "vmla" instuction?

[herbert]

I think there is an error in the PM0214 Programming manual "STM32 Cortex® -M4 MCUs and MPUs programming manual". The multiply and accumulate instruction is called "vlma" throuout the whole document. Other programmin manuals (e.g. for STM32H7) as well as the assembler say this must be "vmla" instead.

Hello @herbert​ ,

Thank you for reporting this typo.

Yes you are right, in Arm®v7-M Architecture Reference Manual the Floating-point Multiply Accumulate is called "VMLA".

I confirm the first issue and I reported internally.

Thank you. I am glad this has been noted and will be corrected. It did irritate a few of my students.
