After a lapse of 1/2 bit from a
(2)Data bit + parity bit
The data bit and parity bit are sampled for 1 bit worth of time from the 1/2 start bit. The then state is assumed the data for the corresponding bit. A sequence of the bits are named Bit 0, Bit 1, ..., parity bit, starting from the one closest to the start bit.
(3)Stop bit
The stop bit is a mark level of 1 bit or more. If a space is detected in detecting the stop bit, a framing error results.
