Sending buffer
The character that has to be sent must be entered into this register.
■
If the sending buffer is able to accommodate the character, it is entered into
this buffer. This character will be sent once all previously entered characters
have been sent.
■
Prior to sending characters from the application program, it must be checked
whether the sending buffer is able to accommodate characters. This can be
checked by reading out MR 11.
■
The sending buffer functions according to the FIFO principle. The first charac-
ter entered is sent first.
