This is a 16 bit processor with 40 pins. It has twenty address pins and out of which sixteen are utilized as data pins. This concept of by using similar pins for data andaddress both is called Multiplexing. lt has 16 signals. It may access a memory of 1 MB.(220).
It has 14 registers which are 16 bits wide. There are a set of arithmetic registers, set of pointers (Base and Index registers), set of segment registers. It has Flag register or program status word (PSW) and a instruction pointer.
Instruction queue: It may queue 6 bytes at a time.
