Does anyone have insights into configuring UART port on Renesas RX130 microcontroller for a bit rate of 115200? I have successfully configured for a 9600, 19200, and 38400. I can read from the MCU and write to the MCU via terminal programs such as tera term. I am using the code generator available through e2Studio IDE.. I am using Serial Communication Interface SCI1, from which I have configured RXD1 / P30 (Pin 18) and TXD1 / P26 (Pin 20). Note P30 is port 3 bit 0 and P26 is port 2 bit 6.

Below is the MCU package configuration view enter image description here enter image description here

Below is Code Generator software component configuration view SCI1 enter image description here enter image description here

Has anyone run into similar issues? Thanks for your help!

Note: I am open to exploring Firmware Integration Tool (FIT) to configure UART ports

Try typing 115200 for bit rate. I think the drop down accepts edited values. The internal software will configure the registers appropriately.
