The AUG instruction is a 4-byte NOP, and reserved for future expansion.

BSR Branch to Subroutine
The BSR Branch to SubRoutine instruction pushes the two program counter bytes PCH and PCL onto the stack. It then adds the word-relative signed offset to the program counter. The relative offset is referenced to the address of the BSR opcode + 2, hence, it is relative to the third byte of the three-byte BSR instruction. The return address, on the stack, also points to this address. This was done to make it compatible with the RTS functionality, and to be consistant will other word-relative operations.

CLE Clear Extend Disable Flag
This instruction initializes the extend disable to a 0. This sets the stack pointer to 16 bit mode.
It affects no registers in the microprocessor and no flags other than the extend disable which is cleared.

CPZ Compare Index Register Z To Memory
This instruction performs a two's complement subtraction between the index register Z and the specified memory location. The results of the subtraction are not stored anywhere. The instruction is strict­ly used to set the flags.
CPZ affects no registers in the microprocessor and also does not affect the overflow flag. If the value in the index register Z is equal to or greater than the value in the memory, the carry flag will be set, otherwise it will be cleared. If the results of the subtract- tion contain bit 7 on the N bit will be set, otherwise it will be cleared. If the value in the index register Z and the value in the memory are equal, the zero flag will be set, otherwise it will be cleared.
