z0Or2NÙ åiñ$'ÿUnless stated otherwise, bits are always represented from MSB to LSB (reading left to right) and multi-bytes sequences are big-endian. So, a jump instruction followed by a two byte address would have the following sequence of bytes jump, high address byte, low address byte. # Registers All the registers will start with an initial value of `0x0`. ## Special Purpose Registers There are some special purpose registers that you cannot directly read/write from, these are used by the CPU for its internal state. There are three 16-bit registers for holding significant memory addresses and a single 8-bit register.
