The I_CAL_M value programmed defines the number of times the calendar 1
sequence is repeated before a DIP-2 parity and “1 1” framing words are inserted
The actual CALENDAR_M
into the I_CAL_M field.
Indicates the length of the ingress calendar 1
CALENDAR_LEN
In LVTTL mode, the I_CAL_LEN can be programmed with any value.
In LVDS mode, the I_CAL_LEN should be programmed with 4n-1, where n is an
integer.
Describes the synchronization state of the SPI-4 ingress data path. Refer to Figure
16 SPI-4 Ingress State Machine p.44 for an illustration of out of sync and in sync
state.
0:SPI-4 ingress data path is out of synchronization
1:SPI-4 ingress data path is in synchronization
Indicates the state of the de-skew block in the ingress datapath.Refer to Figure 15
SPI-4 Ingress Block Diagram p.43 for de-skew overview.
0: SPI-4 ingress data path de-skew is within range.
1: SPI-4 ingress data path de-skew is out of range.
Describes the availability state of the SPI-4 ingress data clock.
0:SPI-4 ingress data clock is not available.
1:SPI-4 ingress data clock is available.
The SPI-4 ingress status channel mode (LVDS/LVTTL) is configured by LVDSSTA
pin and this pin’s level is indicated in the LVDS_STA field.
0:LVTTL mode.
1:LVDS mode.
