Table 5-8: Wake signal features
Feature
Purpose Wake Host interface
Wake host when a predetermined condition is satisfied (for
•
example, when a call is received).
Implementation Low = On
•
Active low, 1.8 V logic.
•
During the powered-off state, this pin may not be in a high
•
impedance state. The host side must implement appropriate
measures to accomodate this.
