Technical Data — MC68HC912DT128A
A — See “accumulators (A and B or D).”
accumulators (A and B or D) — Two 8-bit (A and B) or one 16-bit (D) general-purpose registers
acquisition mode — A mode of PLL operation with large loop bandwidth. Also see ’tracking
address bus — The set of wires that the CPU or DMA uses to read and write memory locations.
addressing mode — The way that the CPU determines the operand address for an instruction.
ALU — See “arithmetic logic unit (ALU).”
analogue-to-digital converter (ATD) — The ATD module is an 8-channel, multiplexed-input
arithmetic logic unit (ALU) — The portion of the CPU that contains the logic circuitry to perform
asynchronous — Refers to logic circuits and operations that are not synchronized by a common
ATD — See “analogue-to-digital converter”.
B — See “accumulators (A and B or D).”
baud rate — The total number of bits transmitted per unit of time.
BCD — See “binary-coded decimal (BCD).”
