CPU STOP FUNCTIONALITY
CPU_STOP# ASSERTION (TRANSITION FROM ‘1’ TO ‘0’)
to the CPU output of interest is programmed to a ‘0’, CPU output will stop CPU_True = High and CPU_Complement = Low. When the SMBus CPU_STOP#
tri-state bit corresponding to the CPU output of interest is programmed to a ‘1’, CPU outputs will be tri-stated.
CPU_STOP# - DE-ASSERTION (TRANSITION FROM ‘0’ TO ‘1’)
is two to six CPU clock periods. If the control register tristate bit corresponding to the output of interest is programmed to ‘1’, then the stopped CPU outputs will
be driven High within 10nS of CPU_STOP# de-assertion to a voltage greater than 200mV.

CPU_STOP#
The CPU_STOP# signal is an active low input controlling the CPU outputs. This signal can be asserted asynchronously.
Asserting CPU_STOP# pin stops all CPU outputs that are set to be stoppable after their next transition. When the SMBus CPU_STOP tri-state bit corresponding
With the de-assertion of CPU_STOP# all stopped CPU outputs will resume without a glitch. The maximum latency from the de-assertion to active outputs
