Dear all,
I have been using LPC1768 UART for a while now. So far I have always set the trigger level to 1 byte and have not really used FIFO. Now I am intended to set the trigger level to 14 bytes, but I do not understand how that works. After 14 bytes are received, the UART asserts a receive interrupt and we will have 14 bytes in receive FIFO.
The question is how am I supposed to read these 14 bytes? Can it be done through RBR register? because that is the only register I know that gives access to receive FIFO.
Thanks in advance for helping me.
