An AXI/APB isolation block programming model when using AXI as a slave is listed in the following steps.

1.Enable the slave response by configuring the ISO_AIBAXI_TYPE (0xFF413038) register for a specific slave.


RECOMMENDED:   AMD recommends configuring this register during boot time and not changing it later.

2.Request for the isolation by writing into the ISO_AIBAXI_REQ (0xFF413030) register depending on the slave to be isolated.

3.Wait for the acknowledgment by polling the ISO_AIBAXI_ACK (0xFF413040) register.


RECOMMENDED:   AMD recommends holding the request until there is an acknowledgment.
