OSOC  
Output  
L7 In all bus modes, OSOC is updated on the rising  
edge of OFCLK. When not presenting valid data,  
OSOC is high impedance.  
In SCI-PHY/Utopia bus slave mode (OMASTER =  
0, OANYPHY = 0) the output port start of cell  
(OSOC) indication signal marks the first word of the  
cell transfer on the ODAT[15:0] data bus. OSOC is  
driven immediately upon sampling OENB low if the  
previous polling cycle resulted in this device being  
selected (see the OCA description below).  
In Any-PHY bus slave mode (OMASTER = 0,  
OANYPHY = 1) the output port start of cell (OSOC)  
indication signal marks the second word of the cell  
transfer on the ODAT[15:0] data bus. OSOC is  
driven after one OFCLK cycle delay upon sampling  
OENB low if the previous polling cycle resulted in  
this device being selected (see the OCA description  
below). Autonomous deselection occurs after the  
last word of a cell resulting in setting OSOC high-  
impedance until reselection.  
In SCI-PHY/Utopia bus master mode (OMASTER =  
1, OANYPHY = 0) the output port start of cell  
(OSOC) indication signal marks the first word of the  
cell transfer on the ODAT[15:0] data bus. OSOC is  
valid coincident with OENB assertion..  
When OANYPHY is high, autonomous deselection  
occurs after the last word of a cell resulting in  
setting OSOC high-impedance until reselection.  
This output is only active if the SCIANY input is a  
logic high.
