(Modem to Application Processor)
Bit transmission in both directions occurs over a two-wire (DATA+FLAG) serial
interface. The bits are transmitted sequentially, starting with the most significant bit
of the physical layer frame. The DATA line always reflects the value being
I
transmitted and the FLAG only toggles when the bit value transmitted remains
constant. (Modem to Application Processor)
The READY-signal indicates that the transmission of a new physical layer frame can
I
begin. (Application to Modem)
The WAKE-signal is used to indicate to the receiver that the transmitter is willing to
O
start a transmission.(Application to Modem)
