[APB] Assert timing of PSTRB and PPROT

Hi All,

I have a question about assert timing of PSTRB and PPROT.

I think APB4 spec (IHI0024C_amba_apb_protocol_spec.pdf) does not describe when PSTRB and PPROT should be asserted.
I guess these signals should be asserted while PSEL is high like PADDR and PWDATA.

Is my understanding correct?

Regards,
Taichi Ishitani

Why have you posted this under 'Infrastructure Solutions' ?

Especially when you've already posted it in the SoC Design forum:
