PTYP
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]
Description
no prepended word
“Word 1” only is included
00

“Word 1:” and “Word2” are included
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].
