CPU_STOP#
I
3.3V-tolerant input for stopping CPU outputs
During direct clock off to M1 mode transition, a serial load of BSEL data is driven
on CPU_STOP# and sampled on the rising edge of PCI_STOP#. See Figure 13
for more information.
38
PCI_STOP#
I
3.3V-tolerant input for stopping PCI and SRC outputs
During direct clock off to M1 mode transition, a serial load of BSEL data is driven
on CPU_STOP# and sampled on the rising edge of PCI_STOP#. See Figure 13
for more information.
