PxTFD—Port [3:0] Task File Data Register (D31:F2)
Address Offset:
Default Value:
This is a 32-bit register that copies specific fields of the task file when FISes are received. The

Power On Device (POD) — RO . Cold presence detect not supported. Defaults to 1.
Spin-Up Device (SUD) — R/W / RO
This bit is R/W and defaults to 0 for systems that support staggered spin-up (R/W when CAP.SSS
(ABAR+00h:bit 27) is 1). Bit is RO 1 for systems that do not support staggered spin-up (when
CAP.SSS is 0).
0 = No action.
1 = On an edge detect from 0 to 1, the ICH6 starts a COMRESET initialization sequence to the
Start (ST) — R/W . When set, the ICH6 may process the command list. When cleared, the ICH6 may
not process the command list. Whenever this bit is changed from a 0 to a 1, the ICH6 starts
processing the command list at entry 0. Whenever this bit is changed from a 1 to a 0, the PxCI
register is cleared by the ICH6 upon the ICH6 putting the controller into an idle state.
Refer to section 12.2.1 of the Serial ATA AHCI Specification for important restrictions on when ST
can be set to 1.
Reserved
Error (ERR) — RO . Contains the latest copy of the task file error register.
