Description
Device Select. DEVSEL# indicates that the driving
device has decoded its address as the target of the
current access. As an input, DEVSEL# indicates
whether any device on the bus has been selected.
DEVSEL# is also driven by any agent that has the
ability to accept cycles on a subtractive decode
basis. As a master, if no DEVSEL# is detected
within and up to the subtractive decode clock, a
master abort cycle results, except for special cycles
that do not expect a DEVSEL# returned.
Request Lines. REQ# indicates to the arbiter that
an agent desires use of the bus. Each master has
its own REQ# line. REQ# priorities are based on
the arbitration scheme chosen.
REQ2# is reserved for the interface with the Geode
CS5536 companion device.
Grant Lines. GNT# indicates to the requesting
master that it has been granted access to the bus.
Each master has its own GNT# line. GNT# can be
pulled away any time a higher REQ# is received or
if the master does not begin a cycle within a set
period of time.
GNT# is an output during normal operation. It is an
input at reset and functions as a boot strap for fre-
quency selection on a board. It must be pulled high
or low to invoke the strap.
GNT2# is reserved for the interface with the Geode
CS5536 companion device.
