ALARMS_TO_PAP

[55:48]

R 0h

JESD alarms going to PAP.

[55:48] = SRX3/7 JESD errors

Each of the bits for the above mentioned lane errors are

mapped as :

bit7 = JESDB: multiframe alignment error

bit6 = JESDB: frame alignment error

bit5 = JESDB: link configuration error

bit4 = JESDB: elastic buffer overflow (bad RBD value)

bit3 = JESDB: elastic buffer match error. The first non-/K/

doesnt match 'match_ctrl' and 'match_data' programmed

values

bit2 = JESDB: code synchronization error

bit1 = JESDB: 8b/10b not-in-table code error

Bit0 = JESDB: 8b/10b disparity error

bit7 = JESDC: EoEMB alignment error

bit6 = JESDC: EoMB alignment error

bit5 = JESDC: cmd-data in crc mode not matching with spi

bit4 = JESDC: elastic buffer overflow (bad RBD value)

bit3 = JESDC: TIED to 0.

bit2 = JESDC: extended multiblock alignment error

bit1 = JESDC: sync-header invalid error ('11' or '00' received

in expected sync header location)

Bit0 = JESDC: sync-header CRC error

Note: Refer to the TI application note for details on error

interpretation.
