6.5.3 Responding to a PCI Access During Suspend  
Mode  
the PCI access is completed, the GXm processor will  
assert SUSPA# and return to a SUSP#-initiated Suspend  
mode. If it was a HALT-initiated Suspend mode and no  
active interrupts have been recognized, the CPU will  
assert SUSPA# and return to a HALT-initiated Suspend  
mode.  
The GXm processor can temporarily exit Suspend mode  
to handle PCI accesses. If an unmasked REQx# is  
asserted, the GXm processor will deassert SUSPA# and  
exit the Suspend mode to respond to the PCI access. A  
PCI access is completed when FRAME# is inactive and  
TRDY# or STOP# are active. If SUSP# is asserted when
