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 I2C
CPU_STOP tri-state bit corresponding to the CPU output of interest is programmed to a '0', CPU output will stop CPU_True
= HIGH and CPU_Complement = LOW. When the I2C 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# - Assertion (transition from '1' to '0')
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 is 2 - 6 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.
