Bit 0 pulses high to indicate that MIF streaming is in progress. However, you only have ~400 Avalon® memory-mapped interface clock cycles after writing to register 0x40140 to read bit 0 as high (1 in the below figure) before the MIF streamer asserts the Avalon® memory-mapped interface waitrequest and locks the Avalon® memory-mapped interface bus (2 in the below figure). After it releases the bus, bit 0 becomes 0, and the new profile is loaded (3 in the below figure).
