Set Sleep Mode

This command causes the CompactFlash Storage 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 timer expires 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 1.6

milliseconds. Note that this time base (1.6 msec) is different from the ATA Specification.

Standby – 96h or E2h
