by 16 should be an integer multiple of the highest bit rate the UART supports. For example, the UARTs in early PCs used a 1.8432-MHz crystal. The crystal’s frequency divided by 16 equals the common bit rate of 115,200 bps. Newer UARTs often use an 18.432-MHz crystal to enable supporting higher bit rates while allowing compatibility with earlier UARTs. In a microcontroller, the chip’s main timing crystal usually serves as a reference for hardware timers that control the UART’s clock. Some microcontrollers, such as Microchip Technology’s PIC18F4520, have an internal frequency multiplier that provides a timing reference four times as fast as the external oscillator’s frequency. To reduce errors, many UARTs take three samples in the middle of each bit and use the logic level that matches two or more of the samples. To avoid detecting brief noise glitches as Start bits, some UARTs read the Start bit a second time in the middle of the bit and accept the Start bit only if the bit has remained a logic low. 16 Formats and Protocols Autodetecting the Bit Rate In many serial-port applications on PCs, the user interface provides a combo box where the user can select a bit rate for the port. The ultimate in user convenience is computers that automatically configure themselves to use the same bit rate. To achieve matching bit rates, one computer we’ll call it the sending computer can detect and match the bit rate of the other computer we’ll call it the receiving computer . There are a couple of ways to implement automatic matching of bit rates. In one approach, the sending computer establishes communications by repeatedly sending a byte. The byte can be any value from 00h to EFh, where the most significant data bit, which is the last bit to transmit, is zero. The receiving computer attempts to receive data at the highest supported bit rate. On detecting a Start bit, the computer must receive data for a period equal to or greater than the time required to read a byte at the low prom-electric.ru
