Hi I am trying to implement hardware flow control using UART on RL78 f-12. I have some doubts- 1. I have connected TXD and RXD pins of the MCU and the module . I have found the CTS and RTS pins on the module but dont know which pins are for RL-78. I have checked the datasheet but I have't found the correct pins. Is hardware flow control supported on RL-78? 2. I found that newer controllers dont have hardware flow control pins, so for CTS and RTS pins of module should go in any GPIO of MCU. My question is what should be the pin assignment? as input or output from CTS and RTS. Cheers Akshay
