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 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 card's sector
buffer.
