The Interrupt Control/Status register is provided at RCS_2488 read/write address 0100.
ROOL_EN:
The Reference Out Of Lock Enable bit connects the ROOL_I status bit to the ECBI_INTB pin
of the RCS_2488. When ROOL_EN is set to logic one, an interrupt on the ECBI_INTB is
generated upon assertion of the ROOL_I register bit. When ROOL_EN is set low, a change
in the ROOL_I status does not generate an interrupt.
DOOL_EN:
The Data Out Of Lock Enable bit connects the DOOL_I status bit to the ECBI_INTB pin of the
RCS_2488. When DOOL_EN is set to logic one, an interrupt on the ECBI_INTB is generated
upon assertion of the DOOL_I register bit. When DOOL_EN is set low, a change in the
DOOL_I status does not generate an interrupt.
LOS_EN:
The Loss of Signal Enable bit connects the LOS_I status bit to the ECBI_INTB pin of the
RCS_2488. When LOS_EN is set to logic one, an interrupt on the ECBI_INTB is generated
upon assertion of the LOS_I register bit. When LOS_EN is set low, a change in the LOS_I
status does not generate an interrupt.
FIFO_UNDF_EN:
The FIFO Underflow Enable bit connects the FIFO_UNDF_I status bit to the ECBI_INTB pin
of the RCS_2488. When FIFO_UNDF_EN is set to logic one, an interrupt on the ECBI_INTB
