Description
PCI transaction will be split into multiple transactions. Max size:
000 = 8 data phase
001 = 16 data phase
010 = 32 data phase
011 = 64 data phase
100 = 128 data phase
101 = 256 data phase
110 = 512 data phase
111 = No restriction in transfer length
Initiate DMA transaction. This bit is cleared by the DMA engine
when it begins its operation.
Command to be used for DMA. This field is restricted to memory
type or IO type commands as defined in the PCI 2.2 spec.
Live XIO_ACK status bit.
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
68360: Not used.
NOR: WN time low
NAND: WEN profile, [15:14] low time; [17:16] high time
IDE: DIOR and DIOW low time
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.
Starting address offset from start address of XIO aperture, in 8M
increments. This field must be naturally aligned with the size of the
profile.
