DCIFI

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.
