Context, Motivation & Description
Apb3CCToggle
does not consider thePSEL
signal. The internal state machine is activated by bus traffic for other slaves. Under the right timing conditions this can lead to the input side of the CDC replying to transactions too early, giving wrong read data.The fix is to make
Apb3CCToggle
look at thePSEL
signal before performing work.Impact on code generation
None, except for slightly changed component logic.
