ATA Command Description
SanDisk CompactFlash Card OEM Product Manual
If the Sector Count Register contains a valid value 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.

Set Sleep Mode–99H, E6H
This command causes the card 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 read to sleep timer is 5 milliseconds. This time base (5
msec) is different from the ATA Specification.
