PHY ready timer. These ten bits specify the timeout value of the PHY_READY timer. If
EN_PHY_TO is set, the link layer will count down on every rising edge of scanTxClk, as long
as PHY_READY is de-asserted. When the counter reaches 0, a PHY_RESET will be issued
to the PHY to try and re-establish communications with the far end. The timer is initially loaded
with a value equal to the concatenation of {PHY_READY_TIMER, 9b0_0000_0000}.
Align insertion rate. The SATA specification requires that the link layer send a pair of ALIGN
primitives at least every 254 words of data. This is achieved by setting ALIGN_RATE to
‘11111111’. However, for test purposes it is possible to send ALIGNs at a higher rate. This can
be achieved by setting ALIGN_RATE to a lower value (that is, ALIGN_RATE-1); words will be
sent by the link layer between each set of ALIGN primitive pairs.
Note: If SEND_4_ALIGNS is set, one should not set the ALIGN_RATE to be four or less. If
Enable PHY not ready timer. If PHY_READY is de-asserted for a length of time, as specified
by CFG_PHY_READY_TIMER, then this bit, when asserted, enables the link layer to re-issue
a PHY_RESET, thereby re-initiating OOB.
Send four ALIGNs. When asserted, four ALIGN primitives are transmitted at the specified rate,
instead of the normal two ALIGNS.
Rx scramble enable. If this bit is asserted, then descrambling of the receive data is enabled as
per the SATA specification.
Tx scramble enable. If this bit is asserted, then scrambling of the transmit data is enabled as
per the SATA specification.
TX prim junk. If this bit is de-asserted, then scrambled junk data is sent after a CONT primitive,
as per the SATA specification. If this bit is asserted, then the single character 0xDEADBEEF
is sent continuously instead. This is to aid debug.
TX CONT. If this bit is asserted, then the transmission of CONT primitives is enabled. If
de-asserted, then long sequences of repeated primitives can be sent by the link layer.
RX bad CRC. When a rising edge is detected on this bit, it causes a bad CRC to be detected
for the current frame. This bit has to be toggled from a 0 to a 1 to enable this feature.
Tx bad CRC. A bad CRC (inverted value of the correct CRC) value will be transmitted for one
FIS only by the link layer when a rising edge is detected on this signal. This bit has to be
toggled from a 0 to a 1 to enable this feature.
Table 19-19. LinkCfg Field Descriptions (continued)
19-20, controls the configuration of the link layer.
SEND_4_ALIGNS is not set, one should not set the ALIGN_RATE to be two or less.
