DESCRIPTION
LA19-23
D0-D4
LA19 TO LA23.
Upper part of the address register used to determine the position
of the memory of the MX98905 within the system memory map.
MEMW
D6
MEMORY WIDTH.
Sets width of external memory. When this bit is set high, external
memory is accessed as word wide, i.e., in compatible mode, 16 kbytes are available
and 64 kbytes are available in noncompatible mode (only when EN16 is set high
also). When it is low, external memory is accessed as byte wide, so only 8 kbytes
of memory are available in compatible mode and 32 kbytes of memory are available
in noncompatible mode.
EN16
D7
ENABLE 16 BIT.
Allow 16-bit system accesses to external memory when it is high.
M16L output will be generated in this mode. When low, only 8-bit accesses are
allowed, and M16L will stay high.
