The host/agent reset configuration inputs, shown in
or as an agent of a master on another interface. In host mode, the MPC8544E is immediately enabled to
master transactions to the PCI interface. If the MPC8544E is an agent on the PCI or PCI Express interfaces,
then the MPC8544E is disabled from mastering transactions on that interface until the external host
enables it to do so. The external host does this by setting the control registers of the MPC8544E’s interfaces
appropriately. See details in the PCI and PCI Express, programming models described in
Bus Interface,”
Note that the values latched on these signals during POR are accessible through the memory-mapped
PORBMSR (POR boot mode status register) described in
Register (PORBMSR).”
