z When write control "EN" = 1 or "EN↑" ( P instruction) changes from 0 to 1, will write the write bit (INB) into
the Nth bit of register D.
z When the operand is 16 bit, the effective range of N is 0~15. For 32 bit ( D instruction) operand it is 0~31. N
beyond this range, will set the N value error flag "ERR" to 1, and do not carry out this instruction.
