36.3.29 FIFO Clear Register 0 (FCLR0)
FCLR is a one shot register to clear the FIFO buffers for endpoints 0 to 3. Writing 1 to a bit clears
the data in the corresponding FIFO buffer.
In case of reception FIFO, by writing data in the FIFO buffer, the data by which PKTE in TRG is
not written to 1 and the data enabled by writing 1 can be cleared. In case of OUT FIFO, the data of
which reception has not been completed can be cleared.
Both sides of the dual-configuration FIFO buffers (EP1 or EP3) can be cleared.
The corresponding interrupt flag is not cleared by this clear instruction. Do not clear a FIFO buffer
during transmission and reception.
