Command (7)
Command (7)
This command enables the ATA Flash Disk Controller to perform Read and Write-Multiple operations
and establishes the block count for these commands. The Sector Count register is loaded with the
number of sectors per block. Upon receipt of the command, the ATA Flash Disk Controller sets BSY to 1
and checks the Sector Count register.
If the Sector Count register contains a valid value (see Section 11.2.1.6.12 for details) and the block
count is supported, the value is loaded for all subsequent Read-Multiple and Write-Multiple commands
and execution of those commands is enabled. If a block count is not supported, an Aborted Command
error is posted, and Read-Multiple and Write-Multiple commands are disabled. If the Sector Count
register contains 0 when the command is issued, Read and Write-Multiple commands are disabled. At
power on, or after a hardware or (unless disabled by a Set Feature command) software reset, the
default mode is Read and Write-Multiple disabled.
This command causes the ATA Flash Disk Controller to set BSY, enter the Sleep mode, clear BSY and
generate an interrupt. Recovery from sleep mode is accomplished by simply issuing another command
(a reset is permitted but not required). Sleep mode is also entered when internal timers expire so the
host does not need to issue this command except when it wishes to enter Sleep mode immediately. The
default value for the timer is 15 milliseconds.
