Help with disassembling MIPS-32 bit instructions
Having trouble disassembling. I know opcode is usally the first 6 bits and then that determines the rest of instruction whether valid or not.
Need help filling in blanks.
| Address | Instruction | Instruction type (I,R,J) | Assembly Language Instruction | Mistakes in formatted instruction (if any) |
| 00400014 | 000000C0 | |||
| 004000C4 | F504050E | |||
| 004000B4 | 14337793 | |||
| 00400020 | 2B169CF5 | |||

Solution
MVI C,00
LDA 4200
MOV B,A
LDA 4201
MOV A,D
MVI A,00
LABEL:ADD B
DCR D
JNZ LABEL
JNC LOOP
INR C
LOOP:STA 4202
MOV A,C
