I need help finding the offsets

 

4. The instruction: 0010101000111111
Extra spaces or no spaces between arithmetic operators will not invalidate an answer.
5. The instruction: 1010001001010101
Extra spaces or no spaces between arithmetic operators will not invalidate an answer.

Treat M[a] as the memory array of 16-bit integers with the index a in the range: x0000,
Assume that the program counter, PC, contains the address of the current instruction and that N = 0 , Z = 0 , P = 1.

Extra spaces among the bits will not invalidate an answer.
After each of the following instructions enter the Java-like assignment statement (but with no semi-colon) which performs what
that specific instruction does in terms of the bits in the instruction itself (with the NZP codes given above) and only using the
names given above. If an instruction does nothing, write nothing
Specify all offests with hexadecimal values; do not insert unneeded zeroes: for example, use x1 not x0001
