3. TECHNICAL BRIEF
3.8.10. UART
There are three UARTs in the MSM6275 ASIC:
• UART1 for data
• UART2 (can be used for USIM interface)
• UART3 (can be used for PM SBI interface)
3.8.11. USB
The MSM6275 device integrates a universal serial bus(USB) controller that supports both
unidirectional and bidirectional transceiver interfaces. The USB controller acts as a USB peripheral
communicating with the USB host. It is also capable of a USB OTG interface to a USB OTG
Transceiver.
3.8.12. SD/MMC interface
The MSM6275 supports a 4-bit (and 1-bit) SD interface, as well as a 1-bit MMC interface. In addition,
the MSM6275 supports SDIO and conforms to the SDIO card specification version 1.10f, including
interrupt support in all modes. SW support is currently not available for SDIO, but will be supported in
a future release.
