Description The contents of the specified data memory location are added with sign-exten-
sion suppressed. The data is treated as a 16-bit unsigned number, regardless
of SXM. The accumulator behaves as a signed number. Note that ADDS pro-
duces the same results as an ADD instruction with SXM = 0 and a shift count
of 0.
