STM32U575: is it possible to disable blocking the read and write accesses to the backup registers, backup SRAM and SRAM2 when the tamper flag is set? To use tamper input for information and not security purpose.

According to RM: "In the NOERASE configuration (TAMPxNOER=1 in the TAMP_CR2 register, ITAMPxNOER=1 in the TAMP_CR3 register), the backup registers and other device secrets are not erased when the corresponding tamper event is detected. In addition, t...

DMA request generation from Software STM32H750

I'm attempting to optimize the amount of instructions/time it takes to move data from CPU to GPIO. When doing ODR = X, I lose about 40ns, closer to 80 because I need to use 2 ODR writes to different ports and in general ODR output seems to sit at abo...
