Bit [01]
:  Buffered Cmd (R) – IDE1 Buffered Command Active.  This bit set indicates that a Buffered Command is 
currently active.  This bit is set when the first command byte is written to the comand buffer.  This bit is cleared 
when all of the task file bytes, including the command byte, have been written to the device. 
Bit [00]
:  Cable 80 (R) – IDE1 Cable 80 Detection.  This bit provides real-time status of the inverted version of 
the IDE1_CBLID_N pin. When set, it indicates that 80 pin cable is detected.

This register defines the PIO timing register for IDE Channel #1 in the SiI 0680A. See chapter 11 for details on 
programming this timing register. The register bits are defined below. 
Bit [31:28]
:  Device 1 Addr Setup Count (R/W) – IDE1 Device 1 Address Setup Time Count for PIO Mode.  This 
bit field is used for programming the address setup time relative to IDE1_DIOR_N and IDE1_DIOW_N in PIO 
mode.   
Bit [27:22]
:  Device 1 Active Count (R/W) – IDE1 Device 1 DIOR_N and DIOW_N Active Time Count for PIO 
Mode.  This bit field is used for programming the active time of IDE1_DIOR_N and IDE1_DIOW_N in PIO mode.  
Bit [21:16]
:  Device 1 Recovery Count (R/W) – IDE1 Device 1 DIOR_N and DIOW_N Recovery Time Count for 
PIO Mode.  This bit field is used for programming the recovery time of IDE1_DIOR_N and IDE1_DIOW_N in PIO 
mode.   
Bit [15:12]
:  Device 0 Addr Setup Count (R/W) – IDE1 Device 0 Address Setup Time Count for PIO Mode.  This 
bit field is used for programming the address setup time relative to IDE1_DIOR_N and IDE1_DIOW_N in PIO 
mode.   
Bit [11:06]
:  Device 0 Active Count (R/W) – IDE1 Device 0 DIOR_N and DIOW_N Active Time Count for PIO 
Mode.  This bit field is used for programming the active time of IDE1_DIOR_N and IDE1_DIOW_N in PIO mode. 
Bit [05:00]
:  Device 0 Recovery Count (R/W) – IDE1 Device 0 DIOR_N and DIOW_N Recovery Time Count for 
PIO Mode.  This bit field is used for programming the recovery time of IDE1_DIOR_N and IDE1_DIOW_N in PIO 
mode.
