11.12 Reading Data Memory
The procedure for reading data memory is similar to
that of reading code memory, except that 16-bit data
words are read instead of 24-bit words. Since less data
is read in each operation, only working registers
W0:W3 are used as temporary holding registers for the
data to be read.
