Question: What is the 'rule of thumb' for an external master when it monitors the FIFO flags to manage under-flow and over-flow conditions?
Answer: "The external master shall never write to a full FIFO, and never read from any empty FIFO." Please refer Sec 8.6.2.3 (Page No. 108) of the EZ-USB Technical Reference Manual for more information on Empty and Full Flags.
