Reserved.
Extended Access Address [5:1]. This extended access register
points to words. ext_a[0] is hardwired to ‘0.’
Extended Access Write Enable. These bits are active-high write
enables for word accesses. If both bits are low, a read is performed. If
ext_we[1] is high, the contents of ext_d[15:8] are written, and if
ext_we[0] is high, the contents of ext_d[7:0] are written. If both bits are
high, both data bytes are written.
Start Access to Extended Memory. Write a ‘1’ to this bit to start the
access to the extended memory registers. This bit is automatically
cleared when the access is complete.
