I am using MCF52259 controller. For data reception through UART I am using the FIFO FFULL interrupt, the FIFO has 4 registers, if i have to receive 6  bytes i will get 1 interrupt for first 4 bytes and i read them, but the problem is when i receive the last 2 bytes of data i wont get interrupt & lose those 2 bytes.

Please provide solution,how to read <4 bytes of data from 4byte FIFO



Thnx & regards
