General: What default state should be used for the HREADY and HRESP outputs from a slave?

Applies to: AHB

Answer

It is recommended that the default value for HREADY is high and the default value for HRESP is OKAY. This combination ensures that the slave will respond correctly to IDLE transfers to the slave, even if the slave is in some form of power saving mode.
