Diagnostic Card Usage

Circular Buffer

The EP-P80P+ has a built-in circular buffer that contains 32 8-bit
wide registers.  The register are used for storage of data entries from
the host chip.  They are indexed 0 through 31, being organized in a
form of circular buffer.  The previous one to the index (i) register
is indexed (i-1), at a lower location; the next one indexed (i+1), at
a higher location.  The last register index (31) is followed with
index (0).  All the registers make a cycle.  In the way, up  32 bytes
of input entries that are most recently transmitted from the EP-
P80P+ can be retained.
