Lower Memory Register Map
This register map shows each byte/word in terms of the
row it is on in the memory. The first byte in the row is
located in memory at the hexadecimal row address in
the left-most column. Each subsequent byte on the row
is one/two memory locations beyond the previous
Register Maps
byte/word’s address. A total of 8 bytes are present on
each row. For more information about each of these
bytes, see the corresponding register description in the
following tables.
