“L” signal equivalent to 1 character bit which is added immediately before the
character bits. It indicates start of data transmission.
Transmit data which is set in the UARTi transmit buffer register.
A signal that is added immediately after the character bits in order to improve data
reliability. The level of this signal changes according to selection of odd/even parity
in such a way that the sum of “1”s in this bit and character bits is always an odd
or even number.
“H” level signal equivalent to 1 or 2 character bits which is added immediately after
the character bits (or parity bit when parity is enabled). It indicates finish of data
transmission.
