Structure
A UART usually contains the following components:
- a clock generator, usually a multiple of the bit rate to allow sampling in the middle of a bit period.
- input and output shift registers
- transmit/receive control
- read/write control logic
- transmit/receive buffers (optional)
- parallel data bus buffer (optional)
- First-in, first-out (FIFO) buffer memory (optional)

Famous quotes containing the word structure:
“Man is more disposed to domination than freedom; and a structure of dominion not only gladdens the eye of the master who rears and protects it, but even its servants are uplifted by the thought that they are members of a whole, which rises high above the life and strength of single generations.”
—Karl Wilhelm Von Humboldt (1767–1835)
“... the structure of a page of good prose is, analyzed logically, not something frozen but the vibrating of a bridge, which changes with every step one takes on it.”
—Robert Musil (1880–1942)
“I really do inhabit a system in which words are capable of shaking the entire structure of government, where words can prove mightier than ten military divisions.”
—Václav Havel (b. 1936)
