BUTTON_MODE
Bit 7
Button mode (100-pin package only). Sets ATAPUEN,
PWR500# and DRVPWRVLD to become button inputs
returned on bits 2, 1, and 0 of EP1IN. This bit must be set to
‘0’ if the 56-pin packages are used.
0 = Disable button mode.
1 = Enable button mode.
Bit 6
Search ATA bus after RESET to detect non-removable ATA
and ATAPI devices. Systems with only a removable device
(like CF readers) must set this bit to ‘0’. Systems with at least
one non-removable device must set this bit to ‘1’.
0 = Do not search for ATA devices.
1 = Search for ATA devices.
Bit 5
Selects the 100- or 56-pin package pinout configuration.
Using the wrong pinout may result in unpredictable behavior.
0 = Use 56-pin package pinout.
1 = Use 100-pin package pinout.
Bit 4
Drive ATA bus when AT2LP is in suspend. For designs in
which the ATA bus is shared between the AT2LP and
another ATA master (such as an MP3 player), the AT2LP
can place the ATA interface pins in a Hi-Z state when it
enters suspend. For designs that do not share the ATA bus,
the ATA signals must be driven while the AT2LP is in
suspend to avoid floating signals.
0 = Drive ATA signals when AT2LP is in suspend.
1 = Set ATA signals to Hi-Z when AT2LP is in suspend.
Bit 3
Reserved. This bit must be set to ‘0’.
Bit 2
Reserved. This bit must be set to ‘0’
Bit 1
Configure the logical polarity of the DRVPWRVLD input pin.
0 = Active LOW (‘connector ground’ indication)
1 = Active HIGH (power indication from device)
Bit 0
Enable the DRVPWRVLD pin. When this pin is enabled, the
AT2LP enumerates a removable ATA device, like Compact-
Flash or MicroDrive, as the IDE master device. Enabling this
pin also affects other pins related to removable device
operation.
0 = Disable removable ATA device support.
1 = Enable removable ATA device support.
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.
