RI5CY: User Manual v4.2-14.5.1 error in complex imaginary multiplication pv.cplxmul.i.*

Created by: alfredoh1234

If using complex convention where rD[15-0] is the real part and rD[31-16 is the imaginary part:

• pv.cplxmul.i.{/,div2,div4,div8} it wrong
  • Current: rD[ 15:0 ] = (rs1[0]*rs2[1] + rs1[1]*rs2[0])>>{15,16,17,18} and rD[ 31:16 ] = rD[ 31:16 ]
  • Should be?: rD[ 31:16 ] = (rs1[0]*rs2[1] + rs1[1]*rs2[0])>>{15,16,17,18} and rD[ 15:0 ] = rD[ 15:16 ]
