Describes the synchronization state of the egress status channel state machine.
0:SPI-4 egress status channel is out of synchronization.
1:SPI-4 egress status channel is in synchronization.
Indicates the state of the de-skew block in the egress status path.Refer to Figure 17
for de-skew overview.
0:SPI-4 egress status path de-skew is within range.
1:SPI-4 egress status path de-skew is out of range.
Describes the availability state of the SPI-4 egress status channel clock.This field is
cleared if there is no status clock available on LVDS or LVTTL input on a 2048
MCLK hopping window.
0:SPI-4 egress status channel clock not available.
1:SPI-4 egress status channel clock is available.
This field is used to force continuous training on the SPI-4 egress datapath.
0:Normal datapath operation.
1:Force continuous training on the SPI-4 egress datapath.
Inserts consecutive DIP-4 error on egress datapath based on the number
E_ERR_INS field will clear itself.
0: Normal datapath operation.
1: Insert DIP-4 error on the SPI-4 egress datapath.
This field is used to program the number of DIP-4 errors to be inserted when the
field E_ERR_INS is set to ‘1’. This number should be less than 16.
The BIT_DELAY field is used to delay SPI-4 egress data bit line 0 by the number of
bits programmed into the BIT_DELAY field. This may be used for diagnostics.
This field enables or disables automatic alignment for the incoming LVDS data bits
in the status path.This register is used for test purposes.
0:Auto alignment is disabled.
1: Alignment is automatic.
programmed in the E_DIP_NUM field. After the DIP-4 errors are inserted, the
