SDMA_TIM—Synchronous DMA Timing Register
(SATA–D31:F5)
Address Offset: 4Ah
Default Value:
This register is R/W to maintain software compatibility and enable parallel ATA
functionality when the PCI functions are combined. These bits have no effect on SATA
operation, unless otherwise noted.

Bit
Reserved
Secondary Drive 0 Cycle Time (SCT0) — R/W. For Ultra ATA mode. The setting of
these bits determines the minimum write strobe cycle time (CT). The DMARDY#-to-
STOP (RP) time is also determined by the setting of these bits.
Reserved
Primary Drive 0 Cycle Time (PCT0) — R/W. For Ultra ATA mode, the setting of these
bits determines the minimum write strobe cycle time (CT). The DMARDY#-to-STOP
(RP) time is also determined by the setting of these bits.
