Data Reception
Rev. 1138F–FPSLI–06/02
Figure 65 shows a block diagram of the UART Receiver.
Figure 65. UART Receiver
Note:
The receiver front-end logic samples the signal on the RXDn pin at a frequency 16 times the
baud-rate. While the line is idle, one single sample of logic 0 will be interpreted as the falling
edge of a start bit, and the start bit detection sequence is initiated. Let sample 1 denote the
first zero-sample. Following the 1-to-0 transition, the receiver samples the RXDn pin at sam-
ples 8, 9 and 10. If two or more of these three samples are found to be logic 1s, the start bit is
rejected as a noise spike and the receiver starts looking for the next 1-to-0 transition.
