Why in CubeMX the sum of the two parameters must be be 32?

[BJX]

New question split from this thread.

Hello,

Thank you for your response. I have double-checked and found that the 6.10 version also cannot be configured in this way. I will adopt the single-line mode on the next hardware version.

However, there is still a question regarding the configuration of can in version 6.16. Why must the sum of the two parameters in the following figure be 32? Otherwise, there will be a warning. In version 6.13, this issue does not exist.

Hello @BJX 

The CubeMX should allow (TX Buffers Nbr + TX FIFO Queue Elmts Nbr ≤ 32 ) instead of ((TX Buffer Nbr + TX Fifo Queue Elmts Nbr) == 32

A ticket (ID: 222211) has been escalated to the development team to address and correct this behavior.

Regarding this point :"Both TX and RX pins must be assigned simultaneously; otherwise, the UART peripheral cannot be enabled." :  MX 6.10.0 and MX 6.16.0 are behaving the same way , in Asynchronous mode  both pins are reserved.
