3.2.1.8 Read Buffer - E4H
The Read Buffer command enables the host to read the current contents of the ADM’s sector buffer.
This command has the same protocol as the Read Sector(s) command
3.2.1.9 Read Multiple - C4H
The Read Multiple command is similar to the Read Sector(s) command. Interrupts are not generated on
every sector, but on the transfer of a block which contains the number of sectors defined by a Set
Multiple command.
Command execution is identical to the Read Sectors operation except that the number of sectors
defined by a Set Multiple command are transferred without intervening interrupts. DRQ qualification of
the transfer is required only at the start of the data block, not on each sector.
The block count of sectors to be transferred without intervening interrupts is programmed by the Set
Multiple Mode command, which must be executed prior to the Read Multiple command. When the Read
Multiple command is issued, the Sector Count Register contains the number of sectors (not the number
of blocks or the block count) requested. If the number of requested sectors is not evenly divisible by the
block count, as many full blocks as possible are transferred, followed by a final, partial block transfer.
The partial block transfer is for n sectors, where
n = remainder (sector count/block count).
If the Read Multiple command is attempted before the Set Multiple Mode command has been executed
or when Read Multiple commands are disabled, the Read Multiple operation is rejected with an Aborted
Command error. Disk errors encountered during Read Multiple commands are posted at the beginning
of the block or partial block transfer, but DRQ is still set and the data transfer will take place as it
normally would, including transfer of corrupted data, if any.
Interrupts are generated when DRQ is set at the beginning of each block or partial block. The error
reporting is the same as that on a Read Sector(s) Command. This command reads from 1 to 256
sectors as specified in the Sector Count register. A sector count of 0 requests 256 sectors. The transfer
begins at the sector specified in the Sector Number Register.
