Setting this bit to a ’1’ will disable the function that delays a PCI bus reset to the
IBM3206K0424 if a serial EPROM is attached and still busy accessing data from the
prior reset. By disabling this function, any PCI requirement to tri-state the I/O drivers
would be met, but EPROM initialization information would be lost.
Setting this bit to a ’1’ will enable the PCORE entity to issue an IBM3206K0424 soft-
ware reset.
Setting this bit to a ’1’ will enable the PCORE entity to issue a processor unit reset.
Setting this bit to a ’1’ will disable using the frequency change detection bit as an inter-
rupt source to INTST.
Setting this bit to a ’1’ will disable using the out-of-phase detection bit as an interrupt
source to INTST.
Setting this bit to a ’1’ will disable using the PLL lock output to make state transitions in
the out-of-phase detection logic.
These bits determine how much time buffering is allowed before an out-of-phase con-
dition is detected. For a value of '000', a value of about 150 ps buffering is used. For
each encoded increment value, an additional 150 ps is added. For example, the
default value of three is about 600 ps of buffering.
Setting this bit to a ’1’ will enable bits 2-0 to override the pffcfg(2-0) bits that are
strapped at the card level.
