Write an assembly program to decrypt the provided data using an XOR Cipher with the given key. The program must first zero out memory locations 0x200 through 0x21F. The assigned string must be stored starting at memory location 0x200. The decrypted text must be stored in memory starting at memory location Ox210. Data: 0x15, 0x29, 0x28, 0x32, 0x61, 0x28, 0x32, 0x61, 0x02, 0x2E, 0x2E, 0x2D, 0x60 Key: 0x41 You must: . . Provide submit zipped project (no tar, no gzip, bzip or anything else) Must zero out all memory from 0x200 to 0x21F (Use Loops) Use assembler directives to get the encrypted data into memory starting at location 0x200 Use assembly loops and various addressing modes to get data in/out of memory during the decryption process The decrypted data must start at memory address Ox210
