>SPLIT 64K
Puts all the odd bytes in the top half of
memory and all the even bytes in the bottom
half. Split moves all 64K, (except location
0000 and location FFFF!)
Using the and keys you can also elect to
SPLIT 128k 256k or 512k bytes.
When a microsystem has a bus which is 16
bits or 32 bits wide, then it will address more
than one PROM in parallel. But the
assembler produces the code in serial fashion,
with high bytes and low bytes alternating. It is
possible that S4 will receive serial code and
must put every other byte in a different
PROM. Splitting the code moves the bytes to
a contiguous block of memory which may be
burned directly into a PROM.
