Bits 7:6
Reserved. Must be set to zero.
Bits 5:0
GPIO[5:0] Input and output control. GPIOs can be individ-
ually set as inputs or outputs using these bits.
0 = Hi-Z (pin is an input). The state of the signal connected
to GPIO input pins is reported in the SYSIRQ or HID data.
1 = Output enabled (pin is an output). The state of GPIO
output pins is controlled by the value in address 0x0A.
Bits 7:6
Reserved. Must be set to zero.
Bits 5:0
These bits select the value driven on the GPIO pins that are
configured as outputs in configuration address 0x09.
0 = Drive the GPIO pin LOW
1 = Drive the GPIO pin HIGH
This byte is a pointer to the start of a 24 byte ASCII
(non-Unicode) string in the EEPROM that is used as the
LUN0 device identifier. This string is used by many operating
systems as the user-visible name for the drive. If this byte is
0x00, the Identify Device data from the drive is used instead.
This byte is a pointer to the start of a 24 byte ASCII
(non-Unicode) string in the EEPROM that is used as the
LUN1 device identifier. This string is used by many operating
systems as the user-visible name for the drive. If this byte is
0x00, the Identify Device data from the drive is used instead.
Number of 20-ms ticks to wait between AT2LP startup or
reset, and the first attempt to access any drives.
Bits 7:5
Must be set to zero.
Bit 4
Enable bus-powered HDD support. This bit enables the use
of DRVPWRVLD features without reporting the LUN0 device
as removable media.
0 = LUN0 is removable media or DRVPWRVLD is disabled
1 = LUN0 device is bus-powered and non-removable
Bit 3
Enable UDMA transfers for removable devices. Some CF
devices interfere with UDMA transfers when more than one
drive is connected to the ATA bus.
0 = Do not use UDMA transfers with removable devices
(UDMA signals are not connected to the CF pins).
1 = Allow UDMA transfers to be used with removable
devices (UDMA signals are connected to the CF pins).
Bits 2:1
Assume the presence of devices and do not perform a
search of the ATA bus to discover the number of LUNs.
00 = Search ATA bus and determine number of LUNs
01 = Assume only LUN0 present; no ATA bus search
10 = Assume LUN0 and LUN1 present; no ATA bus search
11 = Assume LUN0 and LUN1 present; no ATA bus search
