When data is output on the AUXD data lines, the AUX_V signal becomes
active for one clock cycle. The maximum burst rate through this port is
27 Mbyte/s. The user can program all 32 PIDs to be output.
The AUX port can be useful for recording programs into an external stor-
age device, or downloading programs, games, or other information to a
personal computer.
A special bit in the L64007 Mode Register can change this AUX port to
an L64002 host interface connection. If programmed to support the direct
connection to the L64002 via parallel port, the AUX port interface feature
is not supported.
The host processor can access the L64002 through the L64007 using
the built-in feature that generates chip-select to the L64002. The L64007
