RL78/G13 - UART0 issue in uart_printf


We are using UARTS for RL78/G13, CCRL & e2 studio.

We have written a code to use UART0, UART1, and UART2 [ rl78 64pins ].

The which is written for UARTs 1 & 2 is working properly but the same code which is written is not working. API function calls will be changed for UART0,1,2.

In UART0 are we missing some considerations which must be taken to work?

If you have any sample codes or notes guide us.

Thank you
