to 16 for
Rm
Operation
The
Saturates two signed 16-bit halfword values of the register with the value to saturate from
selected by the bit position in n.
Writes the results as two signed 16-bit halfwords to the destination register.
The
Saturates two unsigned 16-bit halfword values of the register with the value to saturate from
selected by the bit position in n.
Writes the results as two unsigned halfwords in the destination register.
Restrictions
Do not use SP and do not use PC
Condition Flags
These instructions do not affect the condition code flags.
If saturation occurs, these instructions set the Q flag to 1.
