num: Number of executed instructions (in decimal)
Number of instructions executed since the CPU was reset
clk: Number of execution clocks (in decimal)
Number of execution clocks since the CPU was reset
pc: Address of executed instructions (in hexadecimal)
code: Instruction codes (in hexadecimal)
bus_addr: Accessed memory addresses (in hexadecimal)
