Description
Multiply MR and the value in
src. The 16 MSBs of the ( (n
s
+3) x 16 ) –bit product
are stored in the PH register. The value in
src is unchanged and the value in
PL is ignored. This instruction rounds the upper 16 bits. Note that A
n is a string
of length n
S
+2, where n
S
is the value in STR register.
