Description
68360: DS time low if using fixed timing.
NOR: OEN time low if not using ACK.
NAND: Delay between address and data phase if not using ACK,
delay until monitoring ACK.
IDE: Not used.
Address offset form start address of XIO aperture, in 8M
increments. This field must be naturally aligned with the size of the
profile.
Sel2 is configured as:
Amount of address space allocated to Sel2 [25,2:1]:
000 = 8M
001 = 16M
010 = 32M
011 = 64M
100 = 128M
Enable sel2 profile.
General Purpose XIO cycle address. This register sets the address
for an indirect read or write to/from XIO address space. Only 4 byte
writes are allowed in this register. The values programmed for bits 0
and 1 are not used by the XIO module. Refer to gpxio_ben.
General Purpose XIO cycle data. This register is programmed with
data for a write cycle.
General Purpose XIO cycle data. This register contains the data of
a read cycle after completion.
1 = GPXIO transaction on XIO is pending.
0 = GPXIO has completed or not yet started.
General Purpose XIO cycle complete. This bit is cleared by writing 1
to bit 6 or 7. It will also be cleared by writing to the GPXIO interrupt
clear register.
1 = Clear “gpxio_done.”
1 = Initiate a transaction on XIO. The type of transaction will match
the profile of the selected aperture. This bit gets cleared if the cycle
has been initiated. This bit clears bit 8 if set.
00 = 68360 type device
01 = NOR Flash
10 = NAND-Flash
11 = IDE
