A Page Format (PF) bit of 1 indicates the SEND DIAGNOSTIC parameters defined
by ANSI standard X3.131-1994 are used. The PF bit specifies the parameter list con-
sists of zero or more diagnostic pages and that the data returned by subsequent
RECEIVED DIAGNOSTIC RESULTS command shall use the diagnostic page for-
mat.
A PF bit of 0 indicates the SEND DIAGNOSTICS parameters are vendor specific.
When the Self Test bit is 1, the PF bit can be 0 or 1 and the parameter list length must
be 0. When the Self Test bit is 0 and the PF bit is 0, the parameter list length must be
0 or 16.
3-4 The Parameter List Length field specifies the length, in bytes, of the SEND DIAG-
NOSTIC parameter list to be transferred from the initiator to the target.
