3. TECHNICAL BRIEF

3.7.16. General-Purpose Input/Output Interface

The MSM6280 device has general-purpose bidirectional input/output pins. Some of the GPIO
pins have alternate functions supported on them. The alternate functions include USB interface,
additional RAM, ROM, general-purpose chip selects, parallel LCD interface, and a UART
interface. The function of these pins is documented in the various software releases.

3.7.17. UART

The MSM6280 device employs three UARTs. UART1 has dedicated pins while UART2 and
UART3 share multiplexed pins.

■

UART1 for data

■

UART2 (can be used for USIM interface)

■

UART3 for data

3.7.18. USB

The MSM6280 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.
