The character is then automatically framed with the start bit, parity bit, correct number of stop bits, and put into the transmit data buffer register. Logic 1 on this line indicates the output register is empty. Reset when a byte is transferred from the buffer to output registers. The clock can be set to 1,16 or 64 times the baud. In Asynchronous Mode, the clock can be set to 1,16 or 64 times the baud.

The device is in "mark status" high level after resetting. Falling edge of TXC shifts the serial data out of the Asynchronous mode-output terminal You just clipped your first slide!

Microprocessor | 8251 USART

As a peripheral device of a microcomputer system, the receives parallel data from the CPU and transmits serial data after conversion. This device also receives serial data from the outside and transmits parallel data to the CPU after conversion. The functional configuration is programed by software. Operation between the and a CPU is executed by program control.
