3.1.3 Jumper Settings for CONFIG 9 or CONFIG 10
CONFIG 9: Used to configure the LAN9353 in Dual RMII mode by using jumpers as
shown below in Table 3-9.
Port 0: RMII PHY, RMII MAC modes
Port 1: RMII MAC, RMII PHY modes
Port 2: Internal PHY
CONFIG 10: Used to configure the LAN9353 in Single MII/RMII/TMII mode by using
jumpers as shown below in Table 8
Port 0: MII MAC, MII PHY, RMII PHY, RMII MAC, TMII MAC, TMII PHY modes
Port 1: Internal PHY
Port 2: Internal PHY

Note: For Switches to short 1-3, Knob Position should be at 1-2 and vice versa.
3.1.4 Link Partner Duplex/Speed Configurations
CONFIG 9 or CONFIG 10 must be configured before Link partner Duplex/Speed con-
figurations. For a detailed jumper settings for CONFIG 9 or CONFIG 10 refer to section
3.1.3.
The “duplex_strap_0” strap from J28 is used to determine the link partners duplex abil-
ity when in Port 0 MII MAC and RMII MAC modes as shown below in Table 3-10.
The “speed_strap_0” strap from J29 is used to determine the link partners speed ability
and to determine the parallel detect speed when in Port 0 “MII MAC and RMII MAC”
modes as shown below in Table 3-10.
