HUAWEI MU736 HSPA+ M.2 Module
Hardware Guide
The GPIO0~7 pins have configurable assignments. There are 4 possible functional
pin out configurations. These 4 configurations are called Port Config0~3. In each Port
Configuration each GPIO is defined as a specific functional pin. The GPIO pin
assignment can see in Table 3-14 . MU736 supports Config0. But the audio function is
not implemented in MU736.
