Hi Kerem, I have the FIFO enabled and I was using RX trigger level of 0 (i.e 1 character). With this setting, I was pretty sure I will get a RDA everytime I recieve a character, but I dont. When I started seeing these CTIs, I tried increasing the trigger to 4 and even 8 and I still see only CTIs, which is not too puzzling. But with 1 character trigger I am really baffled as to why I see CTI interrupts.
