Note: For Switches to short 1-3, Knob Position should be at 1-2 and vice versa.
Note: SW8 will be used for Port 0 when LAN9353 is configured in Single
MII/TMII/RMII Mode and SW8 will be ignored when LAN9353 is in Dual
RMII mode.
P1 Mode configuration straps (SW10, SW8, SW6 & J5/J8) are used to configure the
hard-straps such as Switch Port 1 Mode Strap (P1_mode_strap[1:0]), Switch Port 1
RMII Clock Direction Strap (P1_rmii_clock_dir_strap) and Switch Port 1 Clock Strength
Strap (P1_clock_strength_strap) as shown below in Table 3-13.
