pointer — Pointer register. An index register is sometimes called a pointer register because its
polarity — The two opposite logic levels, logic 1 and logic 0, which correspond to two different
polling — Periodically reading a status bit to monitor the condition of a peripheral device.
port — A set of wires for communicating with off-chip devices.
prescaler — A circuit that generates an output signal related to the input signal by a fractional
program — A set of computer instructions that causes a computer to perform a desired
program counter (PC) — A 16-bit register in the CPU08. The PC register holds the address of
pull — An instruction that copies into the accumulator the contents of a stack RAM location. The
pullup — A transistor in the output of a logic gate that connects the output to the logic 1 voltage
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
push — An instruction that copies the contents of the accumulator to the stack RAM. The stack
PWM period — The time required for one complete cycle of a PWM waveform.
PMC — Pulse width modulated motor control module
RAM — Random access memory. All RAM locations can be read or written by the CPU. The
RC circuit — A circuit consisting of capacitors and resistors having a defined time constant.
read — To copy the contents of a memory location to the accumulator.
