Start Bit Detection
The receiver uses a 16X clock timing. The start bit could have
occurred as much as one clock cycle before it was detected,
as indicated by the shaded portion (A). The center of the start
bit is defined as clock count 7 1/2. If the receiver clock is a
symmetrical square wave, the center of the start bit will be
located within
±
1/2 clock cycle,
±
1/32 bit or 3.125% giving a
receiver margin of 46.875%. The receiver begins searching
for the next start bit at the center of the first stop bit.
