Identify Device String Pointer
Must be set to zero.
Bits (5:0)
GPIO[5:0] Hi-Z control.
‘0’ = Output enabled (GPIO pin is an output).
‘1’ = Hi-Z (GPIO pin is an input).
Bits (7:6)
Must be set to zero.
Bits (5:0)
If the output enable bit is set, these bits select the value
driven on the GPIO pins.
If this value is 00, the Identify Device data will be taken
from the device. If this string is non-zero, it is used as a
pointer to a 24 byte ASCII (non-Unicode) string in the
EEPROM. This string will be used as the device
identifier. This string is used by many operating systems
as the user-visible name for the device.
Number of 20-ms ticks to wait between RESET and
attempting to access the drive.
Bits (7:4)
Bit (3)
‘1’ = Allow UDMA to be used with removable-media
devices
‘0’ = UDMA will not be used with removable-media
devices
Some CF devices will interfere with UDMA if the UDMA
lines are connected to them. This bit tells the
FIRMWARE if the UDMA lines are connected to the
removable-media device.
Bit (2)
If bits 1 and 2 are both 0, the number of logical units will
be determined by searching the ATA and CF buses for
devices.
Bit (1)
If bits 1 and 2 are both 0, the number of logical units will
be determined by searching the ATA and CF buses for
devices.
Bit (0)
Search for ATA devices when VBUS returns. If this bit is
set, the ATA bus will be searched for ATA devices every
time FIRMWARE is plugged into a computer.
Must be set to 0x00.
Length of device descriptor in bytes.
Descriptor type.
USB Specification release number in BCD.
Device class.
Device subclass.
Device protocol.
USB packet size supported for default pipe.
Vendor ID. Cypress’s Vendor ID may only be used for
evalu ation purposes, and not in released products.
Product ID.
