Bit
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 1 Cycle Time (PCT1) — 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
