Preliminary product information describe products that are in development,
for which full characterization data and associated errata are not yet available.
Specifications and information herein are subject to change without notice.
XhrxFLAG I
(Modem to Application Processor)
XhrxDATA I
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
transmitted and the FLAG only toggles when the bit value transmitted remains
constant. (Modem to Application Processor)
XhtxREADY I
The READY-signal indicates that the transmission of a new physical layer frame can
begin. (Application to Modem)
XhtxWAKE O
The WAKE-signal is used to indicate to the receiver that the transmitter is willing to
start a transmission.(Application to Modem)
XhtxFLAG O
(Application to Modem)
XhtxDATA O
