of
WEN. Data present on Din can be written to a newly selected queue on the second WCLK cycle after

For the 16Q device the WRADD bus is 7 bits. The WRADD bus is a dual purpose address bus. The first

The second function of the WRADD bus is to select the sector of queues to be loaded on to the

during strobed flag mode. The least significant bit, WRADD[0] is used to select the sector of a device to be
placed on the
