6. Idle (code: E3H or 97H): This command causes the PC 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 down 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 PC 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.
11. Read Long Sector (code: 22H or 23H): This command performs similarly to the Read Sector(s)
command except that it returns 516 bytes of data instead of 512 bytes.
12. Read Sector(s) (code: 20H, 21H): This command reads from 1 to 256 sectors as specified in the Sector
Count register. A sector count of 0 requests 256 sectors. The transfer begins at the sector specified in the
Sector Number register.
13. Read Verify Sector (code: 40H or 41H): This command is identical to the Read Sectors command,
except that DRQ is never set and no data is transferred to the host .
14. Recalibrate (code: 1XH): This command is effectively a NOP command to the Card and is provided
for compatibility purposes.
15. Request Sense (code: 03H): This command requests an extended error code after command ends with
an error.
16. Seek (code: 7XH): This command is effectively a NOP command to the Card although it does perform
a range check.
17. Set Features (code: EFH): This command is used by the host to establish or select certain features.
