< li > datain0 and datain1 are the two write busses. Only one is used to
actually write the register word, it is selected by the sel
signal.< / li >
< li > When sel is set to zero datain0 is used to write the register
word, otherwise it will be datain1< / li >
< li > selr, selw : this register file have no decoder, so selr have a
bus width equal to < code class = "docutils literal" > < span class = "pre" > regNumber< / span > < / code > . One bit for each word< / li >
< li > The DpgenRf1r0 variant differs from the DpgenRf1 in that the
register of address zero is stuck to zero. You can write into it,
it will not change the value. When read, it will always return
zero< / li >

< li > The DpgenRf1dr0 variant differs from the DpgenRf1d in that the
register of address zero is stuck to zero. You can write into it,
it will not change the value. When read, it will always return
zero< / li >
