In 1/2 bit from the
(2)Data Bit + Parity Bit
Data bit and parity bit are sampled at 1/2 start bit for time length equal to 1 bit. The state thus sampled is taken as the data for the bit concerned. Bits are named as Bit 0, Bit 1, ..., parity bit counted from the one close to the start bit.
(3)Stop bit
The stop bit is a mark level of 1 bit or more. With "Space" having been detected on detection of a stop bit, framing error takes place.
