hello dear. I opened the documentation for stm32H7xx and am trying to calculate the address. I don't understand what it means?

Address offset: 0x3DCh-0x3ECh

what should I add to the base address?

0x40017400

how to understand and read it?

Address offset: 0x3DCh-0x3ECh

 you wrote all the time 0x- for the 16 system. didn't use 'h'. this caused a misunderstanding. it is possible that some special calculations of these addresses were needed. maybe it meant something more than just the 16 system. it looks more like artistic literature than the documentation.

Table 323 and 326 explains it, although indeed it's somewhat chaotic.

BDTAUPR = 0x380 + 0x5C = 0x3DC

Also table 323 is called "RTIM global register map". I guess "RTIM" was meant to be "HRTIM".
