Features 01H and 81H are used to enable and clear 8-bit data transfer mode. If the 01H feature
command is issued all data transfers will occur on the low order D7-D0 data bus and the IOCS16#
signal will not be asserted for data register accesses.
Features 02H and 82H allow the host to enable or disable write cache in the ATA Flash Disk Controllers
that implement write cache. When the subcommand Disable-Write-Cache is issued, the ATA Flash Disk
Controller should initiate the sequence to flush cache to non-volatile memory before command
completion.
Feature 03H allows the host to select the transfer mode by specifying a value in the Sector Count
register. The upper 5 bits define the type of transfer and the low order 3 bits encode the mode value.
One PIO mode is selected at all times. The host may change the selected modes by the Set-Features
command.
Feature 05H allows the host to enable advanced power management. To enable advanced power
management, the host writes the Sector Count register with the desired advanced power management
level and then executes a Set-Features command with subcommand code 05H. The power
management level is a scale from the lowest power consumption setting of 01H to the maximum
performance level of FEH. Table 11-10 shows these values.
