•

Unrecognized FIS. Indicates that the F-bit has been set in the Serror Diag field. Writing a one to bit 6 or 22 of

the port Interrupt Status Register clears this interrupt condition. This interrupt is enabled or disabled with the

corresponding bit in the port Interrupt Enable Set/Clear Register.

•

Device Exchanged. Indicates that the X-bit has been set in the Serror Diag field. The X-bit is set upon receipt of

a COMINIT from the device. Writing a one to bit 7 or 23 of the port Interrupt Status Register clears this interrupt

condition. This interrupt is enabled or disabled with the corresponding bit in the port Interrupt Enable Set/Clear

•

8b/10b Decode Error Threshold Exceeded. Indicates that the 8b/10b Decode Error counter has exceeded the

programmed non-zero threshold value. Writing any value to the port 8b/10b Decode Error Counter Register or

writing a one to bit 8 or 24 of the Interrupt Status Clear Register will clear this interrupt condition. This interrupt is

enabled by writing a non-zero value to the threshold field (bit[31:16]) of the port 8b/10b Decode Error Counter

•

CRC Error Threshold Exceeded. Indicates that the CRC Error counter has exceeded the programmed non-zero

threshold value. Writing any value to the port CRC Error Counter Register or writing a one to bit 9 or 25 of the

Interrupt Status Clear Register will clear this interrupt condition. This interrupt is enabled by writing a non-zero

value to the threshold field (bit[31:16]) of the port CRC Error Counter Register. Writing a zero to the threshold

field will disable this interrupt.

•

Handshake Error Threshold Exceeded. Indicates that the Handshake Error counter has exceeded the

programmed non-zero threshold value. A handshake error occurs when an R_ERR primitive is received. Writing

any value to the port Handshake Error Counter Register or writing a one to bit 10 or 26 of the Interrupt Status

Clear Register will clear this interrupt condition. This interrupt is enabled by writing a non-zero value to the

threshold field (bit[31:16]) of the port Handshake Error Counter Register. Writing a zero to the threshold field will

disable this interrupt.

•

SDB Notify. Indicates that a “Set Device Bits” FIS has been received with the N-bit set in the control field.

ATAPI and Port Multiplier devices optionally use this feature to signal the host that an event has occurred that

requires further scrutiny. Writing a one to bit 11 or 27 of the port Interrupt Status Register clears this interrupt

condition. This interrupt is enabled or disabled with the corresponding bit in the port Interrupt Enable Set/Clear
