Set Multiple Mode command (C6h)
This command enables the 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 card sets BSY 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 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 the default mode is Read and Write Multiple disabled, unless it is disabled by a Set
Feature command.
Table 71.
Set Sleep Mode command (99h or E6h)
This command causes the CompactFlash memory 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. 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 5 milliseconds. Note that this time base (5 ms)
is different from the ATA specification.
