Motorola Mobility LLC T56KT1 User Manual

In case the serial interface incorporates hardware flow control signals, the data will be sent 
according to their state, after the ATS102 delay time has expired.

ATS100 - Defines the application minimal wakeup duration, in seconds, for a single wakeup 
event. This time definition is required to avoid frequent unnecessary wakeup events and 
consequent ATS102 delays.
The application may return to low power mode after the serial interface has been inactive for 
the duration set by ATS100. This duration is measured from the last data sent or received on 
the serial interface.

The following guidelines apply to the wakeup-out mechanism:

G30 will set the WKUPO signal low to indicate that in has data to send through the serial 
interface.

G30 will start sending the data to the application after the delay defined by ATS102.

The WKUPO signal will remain low while data is being sent to the host application.

The host application should keep its serial interface active, and not switch to low power 
mode, while the WKUPO signal is low.

G30 will set the WKUPO signal high when it has completed sending the data.

The application serial interface must stay active, and not switch to low power mode, for the 
duration set by ATS100, after WKUPO is set high.

G30 will not set the WKUPO signal low if it needs to send additional data during the 
ATS100 delay time.

The application may switch to low power mode after the WKUPO signal is set high and the 
serial interface has been inactive for the duration set by ATS100.

The G30 incorporates an internal antenna detection circuit, which senses the physical connection 
and removal of an antenna or antenna circuit on the G30 antenna connector. The antenna 
detection state is reported to the application through the ANT_DET output signal, and may also 
be queried by the ATS97 command.

The detection circuit senses DC resistance to ground on the G30 antenna connector.
