DUAL SERIAL LINK PHY MULTIPLEXER
OSOC
High coincident with the first word of
the cell data structure.
High coincident with the second word
of the cell data structure.
Paused
transfers
Permitted by deasserting OENB
high, but the S/UNI-DUPLEX the
address presented on OADDR[4:0]
Permitted by deasserting OENB high.
The cell transfer resumes
unconditionally when OENB is asserted
must match the content of the Output low again.
Address Match register the last cycle
OENB is high to reselect the device.
Autonomous
deselection
Not supported. A subsequent cell is
output (provided one is available) if
OENB is held low beyond the end of
a cell.
The outputs become high impedance
after the last word of a cell is
transferred until the S/UNI-DUPLEX is
reselected.
The SCI-PHY/Any-PHY Output Configuration register (0x14) determines the cell
format on the output bus. Byte 0 or Word 0 will always contain the channel ID.
The cell length options for the 8 bit bus (shown in Fig. 6) are described in Table
14. 16 bit bus options (shown in Fig. 1) are described in Table 15.
