3.2.1.6 Idle - 97H or E3H
This command causes the CompactFlash card to set BSY, enter the Idle mode, clear BSY and generate
an interrupt. If the sector count is non-zero, it is interpreted as a timer count with each count being 5
milliseconds and the automatic power down mode is enabled. If the sector count is zero, the automatic
power down mode is also enabled, the timer count is set to 3, with each count being 5 ms. Note that this
time base (5 msec) is different from the ATA specification.
3.2.1.7 Idle Immediate - 95H or E1H
This command causes the CompactFlash card to set BSY, enter the Idle mode, clear BSY and generate
an interrupt.
3.2.1.8 Initialize Drive Parameters - 91H
This command enables the host to set the number of sectors per track and the number of heads per
cylinder. Only the Sector Count and the Card/Drive/Head registers are used by this command.
