# --- SAP-1 Program: Test All Instructions with Simple Data ---
# Executes LDA, ADD, SUB, AND, OR, XOR, NOTA sequentially.
# Uses small integer values for easier tracking.
# Expected Intermediate Values (Decimal):
# After LDA: A = 1
# After ADD: A = 1 + 2 = 3
# After SUB: A = 3 - 1 = 2
# After AND: A = 2 & 3 = 2  (0b0010 & 0b0011 = 0b0010)
# After OR:  A = 2 | 1 = 3  (0b0010 | 0b0001 = 0b0011)
# After XOR: A = 3 ^ 4 = 7  (0b0011 ^ 0b0100 = 0b0111)
# After NOTA:A = ~7 = 248 (0b11111000)
# Expected Final Result in Register A: 0xF8 (248 Decimal)

# Opcode DataAddr
# ------ --------
LDA 8   # Addr 0x0: Load Initial Value (1) from Addr 0x8.   A = 1
ADD 9   # Addr 0x1: Add 2 (from Addr 0x9).                  A = 1 + 2 = 3
SUB A   # Addr 0x2: Subtract 1 (from Addr 0xA).             A = 3 - 1 = 2
AND B   # Addr 0x3: AND with 3 (from Addr 0xB).             A = 2 & 3 = 2
OR  C   # Addr 0x4: OR with 1 (from Addr 0xC).              A = 2 | 1 = 3
XOR D   # Addr 0x5: XOR with 4 (from Addr 0xD).             A = 3 ^ 4 = 7
NOTA E  # Addr 0x6: NOT A. (Operand from Addr 0xE ignored). A = ~7 = 248 (0xF8)
HLT F   # Addr 0x7: Halt execution.                         A = 248 (0xF8)
