11.2.1.33 Standby-Immediate - 94H or E0H
This command causes the ATA Flash Disk Controller 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).
11.2.1.34 Translate-Sector - 87H
This command allows the host a method of determining the exact number of times a user sector has
been erased and programmed. The controller responds with a 512 Byte buffer of information containing
the desired cylinder, head, and sector, including its logical address, and the Hot Count, if available, for
that sector. Table 11-14 represents the information in the buffer. Please note that this command is
unique to the ATA Flash Disk Controller.
