10.2.1.18 Set-WP_PD#-Mode - 8BH
This command configures the WP_PD# pin for either the Write-Protect mode or the Power-Down mode.
When the host sends this command to the device with the value AAH in the feature register, the
WP_PD# pin is configured for the Write-Protect mode described in Section 7.1. The Write-Protect
mode is the factory default setting. When the host sends this command to the device with the value 55H
in the feature register, WP_PD# is configured for the Power-Down mode.
All values in the C/D/H register, the Cylinder Low register, the Cylinder High register, the Sector Number
register, the Sector Count register, and the Feature register need to match the values shown above,
otherwise, the command will be treated as an invalid command.
Once the mode is set with this command, the device will stay in the configured mode until the next time
this command is issued. Power-off or reset will not change the configured mode.
10.2.1.19 Standby - 96H or E2H
This command causes the ATA flash disk controller to set BSY, enter the Sleep mode (which
corresponds to the ATA “Standby” Mode), clear BSY and return the interrupt immediately. Recovery
from sleep mode is accomplished by simply issuing another command (a reset is not required).
