BIU Implementation Principles
Since the KSZ8862M 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 12 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.
4.
The asynchronous interface uses RDN and WRN signal strobes for data latching. If necessary, ARDY is de-
asserted on the leading edge of the strobe.
5.
The VLBUS-like synchronous interface uses BCLK, ADSN, and SWR and CYCLEN to control read and write
operations and generate SRDYN to insert the wait state, if necessary, when VLBUSN = 0. For read, the data must
be held until RDYRTNN is asserted.
6.
The EISA-like burst transfer is supported using synchronous interface signals and DATACSN when I/O signal
VLBUSN = 1. Both the system/host/memory and KSZ8862M are capable of inserting wait states. To set the
system/host/memory to insert a wait state, assert RDYRTNN signal. To set the KSZ8862M to insert a wait state,
assert SRDYN signal.
