Hi All,
Please refer to the last line of of Section 9.2.6.2.3.3.1 (sas2r13, 
Page#466)
    --------------------------------
    c) set the Previous Write Data Length state machine variable to the
    Requested Write Data Length
    Xfer_Rdy state machine argument.
    --------------------------------
I am not able to find the defination of Requested Write Data Length 
Xfer_Rdy state machine ardument. Is this the 'write data length' refered 
in bullet (e) of second last para in section 9.2.6.2.2.3(pasted below)
    -------------------------------- second last para in section
    9.2.6.2.2.3, Page#460
    If this state machine receives an ACK Transmitted confirmation for
    an XFER_RDY frame, then this state
    machine shall send an XFER_RDY Arrived message to ST_ITS state
    machine specified by the tag. The
    message shall include the following Xfer_Rdy arguments:
    a) retry data frames;
