set — To change a bit from logic 0 to logic 1; opposite of clear.
shift register — A chain of circuits that can retain the logic levels (logic
signed — A binary number notation that accommodates both positive
SIM — See system integration module (SIM).
software — Instructions and data that control the operation of a
software interrupt (SWI) — An instruction that causes an interrupt and
SPI — See serial peripheral interface module (SPI).
stack — A portion of RAM reserved for storage of CPU register contents
stack pointer (SP) — A 16-bit register in the CPU08 containing the
start bit — A bit that signals the beginning of an asynchronous serial
status bit — A register bit that indicates the condition of a device.
stop bit — A bit that signals the end of an asynchronous serial
subroutine — A sequence of instructions to be used more than once in
1 or logic 0) written to them and that can shift the logic levels to the
right or left through adjacent circuits in the chain.
and negative numbers. The most significant bit is used to indicate
whether the number is positive or negative, normally logic 0 for
positive and logic 1 for negative. The other seven bits indicate the
magnitude of the number.

transmission.
the course of a program. The last instruction in a subroutine is a
return from subroutine (RTS) instruction. At each place in the main
program where the subroutine instructions are needed, a jump or
branch to subroutine (JSR or BSR) instruction is used to call the
subroutine. The CPU leaves the flow of the main program to execute
the instructions in the subroutine. When the RTS instruction is
executed, the CPU returns to the main program where it left off.
