DCIFI:
This bit indicates whether there is a pending interrupt for the Downstream
Cell Interface. If DCIFI is logic 1, at least one interrupt status bit within the
Downstream Cell Interface Interrupt Status register that has its corresponding
enable set is a logic 1.
This bit is not self-clearing; it is only cleared to logic 0 by reading the
Downstream Cell Interface Interrupt Status register.
UCIFI:
This bit indicates whether there is a pending interrupt for the Upstream Cell
Interface. If UCIFI is logic 1, the interrupt status bit in the Upstream Cell
Interface Configuration And Interrupt Status register has its corresponding
enable set and is a logic 1.
This bit is not self-clearing; it is only cleared to logic 0 by reading the
Upstream Cell Interface Configuration and Interrupt Status register.
UPCBI:
This bit indicates whether there is a pending interrupt for the Microprocessor
Cell Buffer. If UPCBI is logic 1, at least one interrupt status bit within the
Microprocessor Cell Buffer Interrupt Control and Status register that has its
corresponding enable set is a logic 1.
This bit is not self-clearing; it is only cleared to logic 0 by reading the
Microprocessor Cell Interrupt Status register.
