BIT MOVE
FUN 42 D P
BITMV
S : Source data to be moved
Ns : Assign Ns bit within S as source bit
D : Destination register to be moved
Nd : Assign Nd bit within D as target bit
S, Ns, D, Nd may combine with V, Z, P0~P9 to
serve indirect address application

z When move control "EN" = 1 or "EN↑" ( P instruction) changes from 0 to 1, will move the bit status specified
by Ns within S into the bit specified by Nd within D.
z When the operand is 16 bit, the effective range of N is 0~15. For 32 bit ( D instruction) operand the effective
range is 0~31. N beyond this range will set the N value error flag "ERR" to 1, and do not carry out this
instruction.
