The default value
(zero). The default value of the counter thresholds is
their maximum
default value of the ETC field is 0b. The default value
of the TMC field is 11b.
If the PCR bit is set to zero, the log parameters is not
reset.
If the SP bit is set to 1 the Drive saves all Log
parameters identified as savable by the DS bit (after
performing the specified LOG SELECT operation).
If the Save Parameter (SP) bit is set to 0, the command
is performed and no parameters are saved.
The page control
parameter values to be selected:
00b :
The initiator can update any or all of the LOG
SELECT parameter threshold values. New threshold
values are transferred as LOG-pages in the DATA-
OUT phase
parameters must be sent in ascending order by the
page/parameter code values.
01b :
The initiator can update any or all of the LOG
SELECT parameter
accumulated values are transferred as LOG-pages in
the DATA-OUT phase of the command. Both the pages
and parameters must be sent in ascending order by
the page/parameter code values.
10b :
All the LOG SELECT threshold values, their ETC and
TMC control
values. See the description of the PCR bit for a
definition of what is meant by default value. No
parameters are transferred and the Parameter List
Length must be 0000h.
11b :
All the
accumulated
reset to their default values. See the description
of the PCR bit for a definition of what is meant
by default value. No parameters are transferred
and the Parameter List Length must be 0000h.
These two bytes specify the length of the parameter list
that will be transferred during the DATA-OUT phase of
the command. A Parameter List Length must neither result
in the truncation of any Log parameter nor exceed the
actual size of the list.
A Parameter List Length of zero is legal and indicates
that no parameters will be transferred.
