I am currently using a MC9S12ZVM Family. I am transmitting some data over the serial communication interface. However on every start up A single Data Byte 0x00 is transmitted. Is there any configuration in processor expert which can stop this.
What do you mean by startup?
When the transmitter gets enabled a preamble of all 1s is loaded into the shift register.
Before that, the port is not controlled by the SCI module.
Which pins do you use for the SCI?
Can you share the project so that I can test it on my side?
