CRC Error Counter Threshold
CRC Error Counter
This register counts the number of Serial ATA CRC Errors that have occurred since last cleared.
Bit [31:16]
: Serial ATA CRC Error Threshold (R/W). This bit field defines the count at which an interrupt will be
asserted. When the count in bits 15:0 is equal to this value, a serial ATA CRC interrupt will be latched. A
threshold value of zero disables interrupt assertion and masks the corresponding interrupt status bit in the Port
Interrupt Status register.
Bit [15:0]
: Serial ATA CRC Error Count (R/WC). This bit field represents the count of Serial ATA CRC errors
that have occurred since this register was last written. Any write to this register will clear both the counter and
the interrupt condition. Clearing the interrupt status bit will also clear the counter. The count will not overflow.
Once this register reaches its maximum count, it will retain that count until cleared to zero by a write operation.
7.3.15 Port Handshake Error Counter
Address Offset: 1048H
Access Type: Read/Write/Clear
Reset Value: 0x0000_0000
31 30 29 28 27 26 25 24 23 22 21 20 19 18 17 16 15 14 13 12 11 10 09 08 07 06 05 04 03 02 01 00
Serial ATA Handshake Error Counter Threshold
Serial ATA Handshake Error Counter
This register counts the number of Serial ATA Handshake Errors that have occurred since last cleared.
Bit [31:16]
: Serial ATA Handshake Error Threshold (R/W). This bit field defines the count at which an interrupt
will be asserted. When the count in bits 15:0 is equal to this value, a serial ATA Handshake interrupt will be
latched. A threshold value of zero disables interrupt assertion and masks the corresponding interrupt status bit
in the Port Interrupt Status register.
Bit [15:0]
:
Serial ATA Handshake Error Count (R/WC).
This bit field represents the count of Serial ATA
Handshake errors that have occurred since this register was last written. Any write to this register will clear both
the counter and the interrupt condition. Clearing the interrupt status bit will also clear the counter. The count will
not overflow. Once this register reaches its maximum count, it will retain that count until cleared to zero by a
write operation.
