List of all instructions in the 8608 architecture.
Instructions are encoded as the opcode, followed by any immediate values.
16-bit immediates are encoded in big-endian byte order.
Each instruction is described in order of: Mnemonic, Opcode, Clock cycles, Description
Control (C):
rst 00 1 Clear all registers and set I=0
