3.2.1.19 Set Sleep Mode- 99H or E6H
This command causes the CompactFlash 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 timer is 15 milliseconds.
3.2.1.20 Standby - 96H or E2H
This command causes the CompactFlash card to set BSY, enter the Sleep mode (which corresponds to
the ATA “Standby” Mode), clear BSY and return the interrupt immediately. Recovery from sleep mode is
accomplished by simply issuing another command (a reset is not required).
3.2.1.21 Standby Immediate - 94H or E0H
This command causes the CompactFlash card to set BSY, enter the Sleep mode (which corresponds to
the ATA “Standby” Mode), clear BSY and return the interrupt immediately. Recovery from sleep mode is
accomplished by simply issuing another command (a reset is not required).
