COMMAND CODE – C6h
The SET MULTIPLE MODE command enables the controller to perform READ
MULTIPLE and WRITE MULTIPLE operations, and establishes the block count
for these commands.
Prior to issuing a command, the host should load the Sector Count Register with
the number of sectors per block. On receiving this command, the drive sets BSY and
checks the contents of the Sector Count Register.
If the Sector Count Register contains a valid value, and the controller supports
block count, the controller loads the values for all subsequent READ MULTIPLE
and WRITE MULTIPLE commands, and enables execution of these commands.
Any unsupported block count in the register causes an Aborted Command error,
and disables execution of READ MULTIPLE and WRITE MULTIPLE commands.
If the Sector Count Register contains a zero value when the host issues the
command, READ MULTIPLE and WRITE MULTIPLE commands are disabled.
Any unsupported block count in the register causes an aborted command error, and
disables READ MULTIPLE and WRITE MULTIPLE commands. After the
command is executed, the controller clears BSY. At power on, the default mode for
the READ MULTIPLE and WRITE MULTIPLE commands is disabled.
