SATADD.H – Saturated Add of Halfwords
Architecture revision:
Architecture revision1 and higher.
Description
Adds the two halfword registers specified and stores the result in destination register. The result
is saturated if it overflows the range representable with 16 bits. If saturation occurs, the Q flag is
set.
