pull — An instruction that copies into the accumulator the contents of a stack RAM location. The stack
pullup — A transistor in the output of a logic gate that connects the output to the logic 1 voltage of the
pulse-width — The amount of time a signal is on as opposed to being in its off state.
pulse-width modulation (PWM) — Controlled variation (modulation) of the pulse width of a signal with
push — An instruction that copies the contents of the accumulator to the stack RAM. The stack RAM
