This register defines the DMA timing register for IDE Channel #0 in the SiI 0680A. See chapter 13 for details on
programming this timing register. The register bits are defined below.
Bit [31:28]
: Device 1 Addr Setup Count (R/W) – IDE0 Device 1 Address Setup Time Count for DMA Mode. This
bit field is used for programming the address setup time relative to IDE0_DIOR_N and IDE0_DIOW_N in DMA
mode.
Bit [27:22]
: Device 1 Active Count (R/W) – IDE0 Device 1 DIOR_N and DIOW_N Active Time Count for DMA
Mode. This bit field is used for programming the active time of IDE0_DIOR_N and IDE0_DIOW_N in DMA mode.
Bit [21:16]
: Device 1 Recovery Count (R/W) – IDE0 Device 1 DIOR_N and DIOW_N Recovery Time Count for
DMA Mode. This bit field is used for programming the recovery time of IDE0_DIOR_N and IDE0_DIOW_N in
DMA mode.
Bit [15:12]
: Device 0 Addr Setup Count (R/W) – IDE0 Device 0 Address Setup Time Count for DMA Mode. This
bit field is used for programming the address setup time relative to IDE0_DIOR_N and IDE0_DIOW_N in DMA
mode.
Bit [11:06]
: Device 0 Active Count (R/W) – IDE0 Device 0 DIOR_N and DIOW_N Active Time Count for DMA
Mode. This bit field is used for programming the active time of IDE0_DIOR_N and IDE0_DIOW_N in DMA mode.
Bit [05:00]
: Device 0 Recovery Count (R/W) – IDE0 Device 0 DIOR_N and DIOW_N Recovery Time Count for
DMA Mode. This bit field is used for programming the recovery time of IDE0_DIOR_N and IDE0_DIOW_N in
DMA mode.
