About connecting between AM3359 and TLK110 for EtherCAT.

Other Parts Discussed in Thread: TLK110, AM3359


Hello,
I am referencing schematic which connecting between AM3359 and TLK110 on ICE and IDK.
AM335x datasheet describes that on ZCZ BALL PRUSS/MII0 Signals are :
(SPRS717B P63: Table 2-32. PRU Subsystem/MII0 Signals Description)

 - pr1_mii0_col [T10]
 - pr1_mii0_crs [T13, V5]
 - pr1_mii0_rxd0 [U4]
 - pr1_mii0_rxd1 [U3]
 - pr1_mii0_rxd2 [U2]
 - pr1_mii0_rxd3 [U1]
 - pr1_mii0_rxdv [T5]
 - pr1_mii0_rxer [V3]
 - pr1_mii0_rxlink [V2]
 - pr1_mii0_txd0 [T2, V13]
 - pr1_mii0_txd1 [R12, T1]
 - pr1_mii0_txd2 [R4, T12]
 - pr1_mii0_txd3 [R3, U12]
 - pr1_mii0_txen [R2, T11]
 - pr1_mii_mr0_clk [V4]
 - pr1_mii_mt0_clk [R1, U10]


But, Both ICE and IDK have not used U1, U2, U3, U4 signals.
Although instead it have used V5, U5, R5, R6, I think they do not have pr1_mii0_xxx function.


Should I use V5, U5, R5, R6?
Can they operate as MII I/F?

Best regards,
RY
