Operation:
If CCR.V == 1,
then if Dx[31] == 0,
then Dx[31:0] = 0x80000000
else Dx[31:0] = 0x7FFFFFFF
else Dx[31:0] is unchanged
Assembler Syntax: SATS Dx
Attributes: Size = long
Description: Update the destination register only if the overflow bit of the CCR is set. If the
operand is negative, then set the result to greatest positive number, otherwise set the result
to the largest negative value. The condition codes are set according to the result.
