PCI_STOP# - Assertion (transition from logic "1" to logic "0")
CPU_STOP# - Assertion (transition from logic "1" to logic "0")
The impact of asserting the CPU_STOP# pin is all CPU outputs that are set in the I
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=Low and CPUC=High. 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.
CPU_STOP# Functionality
0813B—05/17/05
The impact of asserting the PCI_STOP# signal will be the following. All PCI and stoppable PCI_F 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.
