TMC Threshold Met Criteria. Once the criteria 
specified in this field is met and the ETC bit is 1 
and the RLEC bit in MODE SENSE / SELECT 
Control Page is set to 1, then UNIT ATTENTION 
is generated for all initiators.
The criteria for comparison are:
Code - Basis of Comparison
00b - Every update of the cumulative value
01b - Cumulative value equal to threshold value
10b - Cumulative value not equal to threshold 
value
11b - Cumulative value greater than threshold 
value
The Default Threshold Values are the maximum 
values that each parameter can attain.
The Current Cumulative Values are the values 
computed since the last reset of the device (either 
via power-cycle, BUS DEVICE RESET, or SCSI 
RESET).
The Default Cumulative Values are the values to 
which each parameter is initialized at a reset 
condition. Default values are zero.
By default, Current Threshold Values = Default 
Threshold Values.
Note that all types of parameter values are 
changeable via LOG SELECT.
LP List Parameter. This bit should always be set to 0 
to indicate parameter codes are treated as data 
counters.
