CPU_STP# Deassertion
The deassertion of the CPU_STP# signal will cause all
CPUT/C outputs that were stopped to resume normal
operation in a synchronous manner. Synchronous manner
meaning that no short or stretched clock pulses will be
produces when the clock resumes. The maximum latency
from the deassertion to active outputs is no more than 2 CPUC
clock cycles.
Three-state Control of CPU Clocks Clarification
During CPU_STP# and PD# modes, CPU clock outputs may
be set to driven or undriven (three-state) by setting the corre-
sponding SMBus entry in Bit6 of Byte0 and Bit6 of Byte1.
