NOTE
Throughout this section references are made to the auxiliary port and its
specific signals, such as MCKO, MSEO[0:1], MDO[11:0] and others. In
actual use, the device NPC module arbitrates the access of the single
auxiliary port. To simplify the description of the function of the NZ6C3
module, the interaction of the NPC is omitted and the behavior described as
if the module has its own dedicated auxiliary port. The auxiliary port is fully
described in
Section 24.2, “External Signal Description .”
