11-0

This field indicates the maximum average RMS current in mA required during 3.3V or 5V

device operation in CFA power mode 1.

11.2.1.7 Idle - 97H or E3H

This command causes the ATA Flash Disk Controller 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.

11.2.1.8 Idle-Immediate - 95H or E1H

This command causes the ATA Flash Disk Controller to set BSY, enter the Idle mode, clear BSY and

generate an interrupt.
