Recovery Time (RCT) — R/W. The setting of these bits determines the minimum
number of PCI clocks between the last IORDY sample point and the IOR#/IOW# strobe
of the next cycle.
00 = 4 clocks
01 = 3 clocks
10 = 2 clocks
11 = 1 clock
Drive 1 DMA Timing Enable (DTE1) — R/W.
0 = Disable.
1 = Enable the fast timing mode for DMA transfers only for this drive. PIO transfers to
Drive 1 Prefetch/Posting Enable (PPE1) — R/W.
0 = Disable.
1 = Enable Prefetch and posting to the IDE data port for this drive.
Drive 1 IORDY Sample Point Enable (IE1) — R/W.
0 = Disable IORDY sampling for this drive.
1 = Enable IORDY sampling for this drive.
Drive 1 Fast Timing Bank (TIME1) — R/W.
0 = Accesses to the data port will use compatible timings for this drive.
1 = When this bit =1 and bit 14 = 0, accesses to the data port will use bits 13:12 for
Drive 0 DMA Timing Enable (DTE0) — R/W.
0 = Disable
1 = Enable fast timing mode for DMA transfers only for this drive. PIO transfers to the
Drive 0 Prefetch/Posting Enable (PPE0) — R/W.
0 = Disable prefetch and posting to the IDE data port for this drive.
1 = Enable prefetch and posting to the IDE data port for this drive.
Drive 0 IORDY Sample Point Enable (IE0) — R/W.
0 = Disable IORDY sampling is disabled for this drive.
1 = Enable IORDY sampling for this drive.
Drive 0 Fast Timing Bank (TIME0) — R/W.
0 = Accesses to the data port will use compatible timings for this drive.
1 = Accesses to the data port will use bits 13:12 for the IORDY sample point, and bits
the IDE data port will run in compatible timing.
the IORDY sample point, and bits 9:8 for the recovery time. When this bit = 1 and
bit 14 = 1, accesses to the data port will use the IORDY sample point and recover
time specified in the slave IDE timing register.
IDE data port will run in compatible timing.
