Description
63860: 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.
Sel1 is configured as:
00 = 68360 type device
01 = NOR Flash
10 = NAND-Flash
11 = IDE
Amount of address space allocated to Sel1 [25,2:1]:
000 = 8M
001 = 16M
010 = 32M
011 = 64M
100 = 128M
Enable sel1 profile.
Extension field to sel2_offset.
Extension field to sel2_siz.
68360: 1 synchronous DSACK; 0 asynchronous DSACK.
NOR: Not used
NAND: Not used
IDE: Not used
0 = 8 bit XIO device
1 = 16 bit XIO device
0 = Fixed wait state.
1 = Wait for ACK
Not used for IDE
68360: DS time high.
NOR: WN time high
NAND: REN profile, [19:18] low time; [21:20] high time
IDE: DIOR and DIOW high time
63860: Not used.
NOR: WN time low
NAND: WEN profile, [15:14] low time; [17:16] high time
IDE: DIOR and DIOW low time
