bit[1:0] These two bits determine the type of operation to be performed for sequence 1.
The coding is the same as for sequence 3.
For sequence 1, an optional ‘count’ can be specied. If count=0, the sequence is performed only
once. For non-zero counts, the sequence is repeated for count+1 times.
By default, if none of the optional parameters are specied, the rmware will perform an erase
only operation when this command is issued.
The CTPurge™ command structure allows the operation to meet a variety of specied
sanitizing procedures. The table below shows the command entry for each type of specied
sanitizing procedure.
