This section describes some tips for use of the PCI controller.
17.5.1
The PCI controller can power-on in three modes: host mode, agent mode and agent configuration lock
mode. Certain bits in the configuration registers are set differently according to the POR (power-on reset)
mode. Also, certain configuration bits have different implications when compared with past Freescale
parts and PCI implementations. Note that after reset, the device cannot be switched from one mode to
another.
The affected configuration bits are defined in

Controls whether the device can master a transaction on the PCI bus. If cleared, the device
can not master a transaction. This bit is independent of host or agent mode.
Controls the acknowledgement of inbound memory transactions. If cleared, all inbound
memory accesses (including accesses to PCSRBAR space) end in a master abort. This bit
is independent of host or agent mode.
