Revision 1.6
The following is a sample procedure for programming the KSZ8873MLL/FLL/RLL using the SPI bus:
1.
At the board level, connect the KSZ8873MLL/FLL/RLL pins as illustrated in Table 13:

2.
Enable SPI slave mode by setting the KSZ8873MLL/FLL/RLL strap-in Pins P2LED[1:0] to “10”.
3.
Power up the board and assert reset to the KSZ8873MLL/FLL/RLL.
4.
Configure the desired register settings in the KSZ8873MLL/FLL/RLL, using the SPI write or multiple write command.
5.
Read back and verify the register settings in the KSZ8873MLL/FLL/RLL, using the SPI read or multiple read
command.
Some of the configuration settings, such as “Aging enable”, “Auto Negotiation Enable”, “Force Speed” and “Power down”
can be programmed after the switch has been started.
Figure 9 through Figure 12 illustrate the SPI data cycles for “Write”, “Read”, “Multiple Write” and “Multiple Read”. The read data
is registered out of SPIQ on the falling edge of SPIC, and the data input on SPID is registered on the rising edge of SPIC.
