The 9AH Feature is accepted for backward compatibility with the SDP Series but has no impact on the
CompactFlash Memory Card. SanDisk does not recommend the use of this command in new designs.
Features 66H and CCH can be used to enable and disable whether the Power On Reset (POR) Defaults will be set
when a soft reset occurs. The default setting is to revert to the POR defaults when a soft reset occurs. POR defaults
the number of heads and sectors along with 16 bit data transfers and the read/write multiple block count.
5.1.18. Set Multiple Mode—C6H
This command enables the CompactFlash Card 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. The
current version of the CompactFlash Card supports only a block size of 1 sector per block. Future versions may
support larger block sizes. Upon receipt of the command, the CompactFlash Card sets BSY to 1 and checks the
Sector Count Register.
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.
