Bus Interface Unit (BIU)
The BIU host interface is a generic shared data bus interface, designed to communicate with embedded processors. No
glue logic is required when it talks to various standard asynchronous buses and processors.
Supported Transfers
In terms of transfer type, the BIU can support asynchronous transfer or SRAM-like slave mode. To support the data
transfers, the BIU provides a group of signals:
Shared Data bus SD[15:0] for Address, Data and Byte Enable, Command (CMD), Chip Select Enable (CSN), Read
(RDN), Write (WRN) and Interrupt (INTRN).
Physical Data Bus Size
The BIU supports an 8-bit or 16-bit host standard data bus. Depending on the size of the physical data bus, the KSZ8851-
16MLLJ can support 8-bit or 16-bit data transfers.
For example,
For a 16-bit data bus mode, the KSZ8851-16MLLJ allows an 8-bit and 16-bit data transfer.
For an 8-bit data bus mode, the KSZ8851-16MLLJ only allows an 8-bit data transfer.
The KSZ8851-16MLLJ supports internal data byte-swap. This means that the system/host data bus HD[7:0] just connect
to SD[7:0] for an 8-bit data bus interface. For a 16-bit data bus, the system/host data bus HD[15:8] and HD[7:0] only need
to connect to SD[15:8] and SD[7:0] respectively.
Table 4 describes the BIU signal grouping.
Signal
Type
Function
SD[15:0]
I/O
Shared Data Bus
Data D[15:0] -> SD[15:0] access when CMD=0. Address A[7:2] -> SD[7:2] and Byte Enable BE[3:0] ->
SD[15:12] access when CMD=1 in 16-bit mode. Address A[7:0] -> SD[7:0] only access when CMD=1 in 8-
bit mode (Shared data bus SD[15:8] must be tied to low in 8-bit bus mode).
CMD
Input
Command Type
This command input decides the SD[15:0] shared data bus access cycle information.
CSN
Input
Chip Select Enable
Chip Enable asserted (low) indicates that the shared data bus access is enabled.
INTRN
Output
Interrupt
This pin is asserted to low when interrupt occurred.
RDN
Input
Asynchronous Read
This pin is asserted to low during read cycle.
WRN
Input
Asynchronous Write
This pin is asserted to low during write cycle.
