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 (IDE_TIM) 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.
00 = 4 clocks
