Sending characters
Jetter AG
A character is sent by entering it into the register Transmit buffer.
This guide proceeds from the assumption that the user-programmable serial
interface has been configured.
To send characters via user-programmable serial interface proceed as follows:
Step
1
Check the transmit buffer filling level, whether there is enough space in
the transmit buffer.
2
If there is no space in the transmit buffer, wait, until there is enough space.
3
Enter the character to be sent into register Transmit buffer.
Result: The character is written into the transmit buffer and will be sent from
there.
