Character Transmission Diagram

The SCTBI, SCTI, SCRI and SCPI bits have the same functions as SCTBE,

SCTC, SCRC and SCPE bits. The first ones are able to generate interruptions if

the interruptions are enabled in SCIER register while the second ones are only

status bits to be used in polling mode. If the interruption mode is not used, the sta-

tus bits must be used. The SCTBI, SCTI and SCRI bits do not contain valid

information while their respective interrupt enable bits ESCTBI, EXCTI, ESCRI are

cleared.
