Figure 78 Set Multiple Command (C6h)

The Set Multiple command enables the device to perform Read and Write Multiple commands and establishes the block size for these commands. The block size is the number of sectors to be transferred for each interrupt.

The default block size after power up is 0, and Read Multiple and Write Multiple commands are disabled.

If an invalid block size is specified, an Abort error will be returned to the host, and Read Multiple and Write Multiple commands will be disabled.

Output Parameters To The Device

Sector CountThe block size to be used for Read Multiple and Write Multiple commands. Valid block sizes can be selected from 0, 1, 2, 4, 8 or 16. If 0 is specified, then Read Multiple and Write Multiple commands are disabled.
