PTYP:  
The Parity Type (PTYP) bit selects even or odd parity for the OPRTY output  
of the SCI-PHY output port. When set to logic 1, OPRTY completes even  
parity bit for ODAT[15:0] if OBUS8 input is low or for ODAT[7:0] if OBUS8  
input is high. When set to logic 0, OPRTY completes odd parity bits for  
ODAT[15:0] if OBUS8 input is low or for ODAT[7:0] if OBUS8 input is high.  
PRELEN[1:0]:  
The Prepend Length (PRELEN[1:0]) bits determine the number of prepended  
words to each cell  
When OBUS8 is a logic 1, the binary PRELEN[1:0] value indicates whether  
the optional “Word 1” and “Word 2” illustrated in Fig. 6 are included in the  
data structure presented on ODAT[7:0]. The possible values are:  
PRELEN[1:0]

When OBUS8 is a logic 0, only PRELEN[0] is used. When PRELEN[0] is  
logic 1, the optional “Word 1” illustrated in Fig. 7 is included in the data  
structure presented on ODAT[15:0].  
H5UDF:  
The H5UDF bit determines whether or not the H5/UDF octets are included in  
cells transferred over the SCI-PHY/Any-PHY output port. When H5UDF is set
