Part Number: TUSB3210

Hi Sirs,

Sorry to bother you.

We'll refer SM-USB-DIG Platform user guide to design.

Some questions need confirm.

1. Page 5 fig 4 General-purpose I/O port P0 [0.7],P1 [0.7],P2[0.7] Net name is not clear enough. Could you help check it?

2. Page 6 fig 5 If we only use I2C and direct connect to LED. Should we need reserve SPI signal and LVC07A/2G07 ?

3. Page 6 fig 6.

    We use SM-USB-DIG in some of our EVM, but we do not provide support for the design of SM-USB-DIG itself. We do not support the use of SM-USB-DIG outside of TI EVM.
