Note: This applies to all the ASIC Revisions A11 and above.
TX pre-emphasis driver
swing 7:5 000b Port3 Tx driving swing[7:5] is valid for both SATA 3G and
1.5G. It sets the TX pre-emphasis driver strength. The user
can program the optimum pre-emphasis value for each SATA
port if TX pre-emphasis enable bit turned on.

BIST Pattern Count - RW - 32 bits - [PCI_Reg:C0h]
Field Name Bits Default Description
BIST Pattern Count 31:0 0000_20
00h
This count specifies how many Octal WORD pattern need to
be checked before BIST Done bit be set. This count value is
used fro all the 4 ports. 400h default value would be used for
tester, which means 32K DWORD pattern would be compared
for BIST test. Value of “0000_0000”h means the maximum
patterns (16,000, 000, 000) checked.
PCI Target Control TimeOut Counter - RW – 8 bits - [PCI_Reg:C4h]
Field Name Bits Default Description
PCI Target Control
TimeOut Count 7:0 80h This register is used for programming the PCI Target Control
TimeOut Count used to clear any stale target commands to
the hosts controller. Granularity is 15.5us (Count * 15.5 us)
The counter will be disabled if the count is programmed to 0x0.
