ALARMS_CLEAR[
63:56]
R/W 0h
Clear 'alarms' register to the alarm pin; Alarms won't be
generated if '1' so it must be programmed to '0' for alarms to
continue.
[63:56] = SRX4/8 JESD errors
Each of the bits for the above mentioned lane errors are
mapped to :
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
register bits
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.

affect alarm read from SPI.
