... FIFO while the RX demodulator is filling the FIFO. IR FRAMING Framing involves adding wrappers around the payload received from NDIS to make a valid IR frame. MCS7780 uses a custom framing style to achieve low gate count. The hardware and software together play a role in making of SIR, MIR, and FIR frames. Page 5 ...
