V CCP
See the power-up sequencing diagram in Figure 3−2.
1. Assert PERST to the device.
2. Remove the reference clock.
3. Remove V
4. Remove 3.3-V and 1.5-V voltages.
Please see the power-down sequencing diagram in Figure 3−3. If the V
powered after a system shutdown, then the bridge power-down sequence is exactly the same as shown in
Figure 3−3.
