CPU Interface I/O Registers
The KSZ8851M provides an SRAM-like asynchronous bus interface for the CPU to access its internal I/O registers. I/O
registers serve as the address that the microprocessor uses when communicating with the device. This is used for
configuring operational settings, reading or writing control, status information, and transferring packets. The KSZ8851M
can be programmed to interface with either Big-Endian or Little-Endian processor.
I/O Registers
The following I/O Space Mapping Tables apply to 8-, 16- or 32-bit bus interface. Depending upon the bus interface used
and byte enable signals (BE[3:0]N control byte access input pins), each I/O access can be performed the following
operations as an 8-bit for 256 address locations, 16-bit for 128 address locations or 32-bit for 64 address locations.
