PADDR

How to use the PADDR of the APB for receiving and sending data through APB?
AMBA APB

1)what is the difference between with wait state and with no wait state(read/write)?what are the advantages of both in APB?
AMBA APB

1) the APB uses massive memory-I/O accesses.what is that massive memory-I/O accesses?
why PSTRB signal in APB4 have four bits?

PSTRB signal indicates which byte lanes to update during a write transfer. it shows that the bus contain valid data, when PSTRB[3:0]=1111. why we need bus instead of single bit PSTRB signal?
[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...
