+* BIT7 - If EPn use more then one FIFO, then this bit should be on the first
+* BIT6
+* BIT5
+* BIT4 - Block size: 0 - 64/512; 1 - 128/1024. It depends on initial FIFO size.
+* BIT2 - BIT3; number of FIFO blocks or better to say extra blocks? 0 - no more blocks; 1 - one block; 2 - two blocks.
+* BIT0 - BIT1; EP type: 0x1 - Iso; 0x2 - Bulk, 0x3 - Intr;
