PDSP16540 32K BUCKET BUFFER

32 bit input bus. If MD5 is high, pins IP16:31 are redundant 32 bit output bus. This bus will be high impedance until the Data Available Flag is active. It then remains low impedance until the required amount of data has been read. D15:0 become inputs during reset, and may be used to define the oper.
