AM2431: USB feature

Part Number: AM2431

As USB feature on AM2431, my customer is asking about following questions.  

1. Is the USB Host controller compatible with EHCI?

2. Does it have a SOF trigger function?
They plan to use this function that activates the internal timer as a trigger.

For example,  When internal timer reaches a certain , start start UART DMA for data transmission.

    Hi Tohru-san,

    1. The AM2431 SUB Host control is compatible to EHCI (USB 2.0 High Speed)

    2. In device mode, there is a callback function: "busInterval" in CUSBD_Callbacks_s structure for user to plug their own SOF processing function. When the SOF is detected, the USB ISR will call the busInterval to do customized processing.

    Best regards,
