BIU Implementation Principles
Since KSZ8841M 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.
1.
Byte, word, and double word data buses and accesses (transfers) are supported.
2.
Internal byte swapping is not implemented and word swapping is supported internally. Refer to Figure 11 for the
appropriate 8-bit, 16-bit, and 32-bit data bus connection.
3.
Since independent sets of synchronous and asynchronous signals are provided, synchronous and asynchronous
cycles can be mixed or interleaved as long as they are not active simultaneously.
