3.8.10. UART
There are three UARTs in the MSM6250A ASIC:
• UART1 for data
• UART2 (can be used for USIM interface)
• UART3 (can be used for PM SBI interface)
3.8.11. USB
The MSM6250A device integrates a universal serial bus (USB) controller that supports both
unidirectional and bidirectional transceiver interfaces. The USB controller acts as a USB function
communicating with the USB host. The USB controller also supports digital audio through USB
interface and connects directly to the QDSP4000 for the audio processing.
