(46) SET MAX ADDRESS EXT (X’37’)
•
Description
This command limits specifications so that the highest address that can be accessed
by users can be specified only in LBA mode.
The address information specified with this command is set in words 1, 54, 57, 58,
60, 61, and 100 to 103 of the IDENTIFY DEVICE command response. If read or
write processing is executed for an address that is outside of the new address
space, an ID Not Found error occurs.
If the SC field bit is 0 and the value volatile (VV) bit is 1 when this command is
executed, the specified values are maintained after a power-on or a COMRESET.
If the VV bit is 0 when the command is executed, the specified values are
invalidated during the power-on sequence. If the VV bit is 1, the highest address
value is defined as the last value specified. (If the VV bit is not set to 1, the
highest address is the default value.)
After a power-on reset is performed, a host can issue the SET MAX ADDRESS
(EXT) command only once if the VV bit is 1. If the SET MAX ADDRESS (EXT)
command is issued twice or more, an ID Not Found error occurs.
When the SET MAX ADDRESS EXT command is executed, all SET MAX
ADDRESS commands are aborted. The address value returns to the origin when
the SET MAX ADDRESS EXT command is executed using the address value
returned by the READ NATIVE MAX ADDRESS command.
