CPU_STP# Assertion
The CPU_STP# signal is an active LOW input used for
synchronous stopping and starting the CPU output clocks
while the rest of the clock generator continues to function.
When the CPU_STP# pin is asserted, all CPU outputs that are
set with the SMBus configuration to be stoppable are stopped
within two to six CPU clock periods after sampled by two rising
edges of the internal CPUC clock. The final states of the
stopped CPU signals are CPUT = HIGH and CPUC = LOW.
CPU_STP# Deassertion
The deassertion of the CPU_STP# signal causes all stopped
CPU outputs to resume normal operation in a synchronous
manner. No short or stretched clock pulses are produced when
the
clock
resumes.
The
maximum
latency
from
the
deassertion to active outputs is no more than two CPU clock
cycles.
.
Note: *Differential clocks output state can be configured through Byte 19 bits 3:.0
