PCI Bus Request.
In PCI host mode with internal arbiter:
These signals are inputs whose assertion indicates to the internal RC32438
arbiter that an agent desires ownership of the PCI bus.
In PCI host mode with external arbiter:
PCIREQN[0]: asserted by the RC32438 to request ownership of the PCI bus.
PCIREQN[3:1]: unused and driven high.
In PCI satellite mode:
PCIREQN[0]: this signal is asserted by the RC32438 to request use of the PCI
bus.
PCIREQN[1]: function changes to PCIIDSEL and is used as a chip select during
configuration read and write transactions.
PCIREQN[3:2]: unused and driven high.
Note: When the GPIO register is programmed in the alternate function mode for
bits GPIO [24] and [27], these bits become PCIREQN [4] and [5] respectively.
PCI Reset. In host mode, this signal is asserted by the RC32438 to generate a
PCI reset. In satellite mode, assertion of this signal initiates a warm reset.
PCI System Error. This signal is driven by an agent to indicate an address par-
ity error, data parity error during a special cycle command, or any other system
error. Requires an external pull-up.
PCI Stop. Driven by the bus target to terminate the current bus transaction. For
example, to indicate a retry.
PCI Target Ready. Driven by the bus target to indicate that the current data can
complete.
