Bits (7:0)
ATAPI event notification command. The value of this register
(if other than 0x00) is used to identify the vendor-specific
Event Notification command (see Section 5.2.3). Setting this
field to 0x00 disables this feature.
Bits (7:0)
ATA device Automatic Power Management value. If an
attached ATA device supports APM and this field contains
other than 0x00, the CY7C68310 will issue a SET
FEATURES command to enable APM with this register
value during the drive initialization.
Time in 128-millisecond granularity before the CY7C68310
stops polling the ALT STAT register for reset complete and
restarts the reset process (0x80 = 16.4 seconds).
Bit (7) – Read only
USB bus mode of operation.
‘0’ = USB is operating in full-speed mode (12 Mbit/sec)
‘1’ = USB is operating in high-speed mode (480 Mbit/sec)
CBW Command Block Size.
‘0’ = 12 byte ATAPI CB
‘1’ = 16 byte ATAPI CB
Bit (5)
Device number selection. This bit is valid only when “Skip
ATA/ATAPI Device Initialization” is active. Otherwise, the
value of this bit is ignored.
‘0’ = Drive 0 (master)
‘1’ = Drive 1 (slave)
Bit (4)
ATAPI reset during drive initialization.
Setting this bit causes the CY7C68310 to issue an ATAPI
reset during device initialization.
Bit (3) – Read only.
Indicates if an ATA or ATAPI device is detected.
‘0’ = ATAPI device
‘1’ = ATA device or possible device initialization failure
Bit(2)
Force USB full-speed only operation.
Setting this bit prevents the CY7C68310 from negotiating
HS operation during USB reset events.
‘0’ = Normal operation – allow HS negotiation during USB
reset
