Mismatch between HAL and Reference Manual on voltage scale max frequencies
I've noticed that the frequencies written in the reference manual are different from the ones used in the HAL.Is there a good reason they are different? Which ones are correct?I attached a screenshot from page 407 of the reference manual.https://www....
Resolved! Missing info in reference manual
In the STM32L562 reference manual (RM0438), v7.0, the section 11.6.13 "GPIO register map" is missing the registers MODER and PUPDR (which are documented in the preceding sections).
