BIU Implementation Principles
Since the KSZ8842M is an I/O device with 16 addressable locations, address decoding is based on the values of A15-A4
and AEN. Whenever DATACSN is asserted, the address decoder is disabled and a 32-bit transfer to Data Register is
assumed (BE3N – BE0N are ignored).
If address latching is required, the address is latched on the rising edge of ADSN and is transparent when ADSN=0.
