NOTES:
1.
GHI# is ignored until 10
μ
s after BCLK, BCLK# stop or DPSLP# assertion, the setup and hold window must
occur after this time.
2.
BCLK, BCLK# must meet the BCLK AC specification from within 150 ns of turning on (rising above V
IL,BCLK
).
3.
This specification applies to the exit from the Deep Sleep state whether or not an Enhanced Intel SpeedStep
technology operating mode transition occurs.
