SIDETIM—Slave IDE Timing Register (SATA–D31:F2)
Address Offset: 44h
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
Secondary Drive 1 IORDY Sample Point (SISP1) — R/W. This field determines the
number of PCI clocks between IDE IOR#/IOW# assertion and the first IORDY sample
point, if the access is to drive 1 data port and bit 14 of the IDE timing register for
secondary is set.
00 = 5 clocks
01 = 4 clocks
10 = 3 clocks
11 = Reserved
Secondary Drive 1 Recovery Time (SRCT1) — R/W. This field determines the
minimum number of PCI clocks between the last IORDY sample point and the IOR#/
IOW# strobe of the next cycle, if the access is to drive 1 data port and bit 14 of the IDE
timing register for secondary is set.
00 = 4 clocks
01 = 3 clocks
10 = 2 clocks
11 = 1 clocks
Primary Drive 1 IORDY Sample Point (PISP1) — R/W. This field determines the
number of PCI clocks between IOR#/IOW# assertion and the first IORDY sample point,
if the access is to drive 1 data port and bit 14 of the IDE timing register for primary is
set.
00 = 5 clocks
01 = 4 clocks
10 = 3 clocks
11 = Reserved
Primary Drive 1 Recovery Time (PRCT1) — R/W. This field determines the
minimum number of PCI clocks between the last IORDY sample point and the IOR#/
IOW# strobe of the next cycle, if the access is to drive 1 data port and bit 14 of the IDE
timing register for primary is set.
