Preliminary
(1)
Check Power Mode (code: E5h or 98h): This command checks the power mode.
(2)
Execute Drive Diagnostic (code: 90h): This command performs the internal diagnostic tests implemented
by the Card.
(3)
Erase Sector(s)(code: C0h): This command is used to erase data sectors.
(4)
Format Track (code: 50h): This command writes the desired head and cylinder of the selected drive with a
vendor unique data pattern (typically FFh or 00h). To remain host backward compatible, the card expects
one sector (512Bytes) of data from the host to follow the command with same protocol as the Write Sector
Command.
(5)
Identify Drive (code: ECh): This command enables the host to receive parameter information from the
Card.

(6)
Idle (code: E3h or 97h): This command causes the Card to set BSY, enter the Idle mode, clear BSY and
generate an interrupt. If sector count is non-zero, the automatic power down mode is enabled. If the
sector count is zero, the automatic power mode is disabled.
(7)
Idle Immediate (code: E1h or 95h): This command causes the Card to set BSY, enter the Idle(Read) mode,
clear BSY and generate an interrupt.
(8)
Initialize Drive Parameters (code: 91h): This command enables the host to set the number of sectors per
track and the number of heads per cylinder.
(9)
Read Buffer (code: E4h): This command enables the host to read the current contents of the card’s sector
buffer.
(10)
Read Multiple (code: C4h): This command performs similarly to the Read Sectors command.
Interrupts are not generated on each sector, but on the transfer of a block, which contains the number of
sectors defined by a Set Multiple command.
