Features 01H and 81H are used to enable and clear 8-bit data transfer modes in True IDE Mode. If the

01H feature command is issued all data transfers will occur on the low order D7-D0 data bus and the

IOIS16 signal will not be asserted for data register accesses.

Features 55H and BBH are the default features for the CompactFlash card; thus, the host does not

have to issue this command with these features unless it is necessary for compatibility reasons.

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.

3.2.1.18 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. 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.
