R/O
ARF almost-full flag. While the ARF can accept at least one more quadlet, ARFAFl is set to 1. Otherwise
ARFAFl is set to 0. This bit defaults to 0 and is set to 0 on a bus reset.
2
ARFAEm
R/O
ARF almost-empty flag. While the ARF contains only one quadlet, ARFAEm is set to 1. Otherwise
ARFAEm is set to 0. This bit defaults to 0 and is set to 0 on a bus reset.
3
ARFEmp
R/O
ARF empty flag. When the ARF is empty, ARFEmp is set to 1. Otherwise, ARFEmp is set to 0. This bit
defaults to 1 and is set to 1 on a bus reset.
