Power-up reset. PI7C8150B performs the standard power-up reset
functions as described in Section 12.
PME# signals are routed from downstream devices around PCI-to-PCI bridges. PME#
signals do not pass through PCI-to-PCI bridges.

RESET
This chapter describes the primary interface, secondary interface, and chip reset
mechanisms.
12.1
PRIMARY INTERFACE RESET
PI7C8150B has a reset input, P_RESET_L. When P_RESET_L is asserted, the following
events occur:
PI7C8150B immediately tri-states all primary and secondary PCI interface signals.
PI7C8150B performs a chip reset.
Registers that have default values are reset.
P_RESET_L asserting and de-asserting edges can be asynchronous to P_CLK and
S_CLKOUT. PI7C8150B is not accessible during P_RESET_L. After P_RESET_L is de-
asserted, PI7C8150B remains inaccessible for 16 PCI clocks before the first configuration
transaction can be accepted.
12.2
SECONDARY INTERFACE RESET
PI7C8150B is responsible for driving the secondary bus reset signals, S_RESET_L.
PI7C8150B asserts S_RESET_L when any of the following conditions are met:
Signal P_RESET_L is asserted. Signal S_RESET_L remains asserted as long as
P_RESET_L is asserted and does not de-assert until P_RESET_L is de-asserted.
The secondary reset bit in the bridge control register is set. Signal S_RESET_L
remains asserted until a configuration write operation clears the secondary reset bit.
S_RESET_L pin is asserted. When S_RESET_L is asserted, PI7C8150B immediately 3-
states all the secondary PCI interface signals associated with the secondary port. The
S_RESET_L in asserting and de-asserting edges can be asynchronous to P_CLK.
When S_RESET_L is asserted, all secondary PCI interface control signals, including the
secondary grant outputs, are immediately 3-stated. Signals S1_AD, S1_CBE[3:0]#, S_PAR
are driven low for the duration of S_RESET_L assertion. All posted write and delayed
transaction data buffers are reset. Therefore, any transactions residing inside the buffers at
the time of secondary reset are discarded.
