CPU_STOP# - Assertion (transition from logic "1" to logic "0")
PCI_STOP# - Assertion (transition from logic "1" to logic "0")
The impact of asserting the PCI_STOP# signal will be the following. All PCI[6:0] and stoppable PCI_F[2,0] clocks will
latch low in their next high to low transition. The PCI_STOP# setup time tsu is 10 ns, for transitions to be recognized
by the next rising edge.
The impact of asserting the CPU_STOP# pin is all CPU outputs that are set in the I
via assertion of CPU_STOP# are to be stopped after their next transition following the two CPU clock edge sampling
as shown. The final state of the stopped CPU signals is CPUT=High and CPUC=Low. There is to be no change to the
output drive current values. The CPUT will be driven high with a current value equal to (MULTSEL0) X (I REF), the CPUC
signal will not be driven.
