PMU_SPI: This SPI interface is dedicated for the PMU (Hi6421) and works in
three-wire mode (the input end and the output end share the same data signal). Its signal
level is 1.8 V.
BT_SPI: This interface is a dedicated SPI interface between a Bluetooth baseband unit
integrated in the Hi3620 and the RF IC (Hi6350). Its signal level is 1.8 V.
GPS_SPI: This interface is a dedicated SPI interface between a GPS baseband unit
integrated in the Hi3620 and the RF IC (Hi6350). Its signal level is 1.8 V.
ISP_I2C0/1: used for camera I2C interfaces.
I2C0: used for the xSenor, capacitive touchscreen, and independent FM communication
and data interfaces.
I2C1: used for the charging IC.
The xSensor and capacitive touchscreen are components that may be frequently accessed. Therefore, the
preceding I2C bus allocation mode is applied by default but a jumper is reserved during design to
connect the capacitive touchscreen to I2C1.
I2S interface: This interface is a stereo audio interface between the Hi3620 and the codec
inside the Hi6421.
M_PCM interface: This interface provides a voice channel between the modem and the
codec inside the Hi6421.
BT_PCM interface: This interface provides a voice channel between external third-party
Bluetooth devices and the codec inside the Hi6421.
USB_NANO interface: This interface statically supports USB 2.0 hosts and devices.
USB_PICO interface: This interface supports USB2.0 devices and BC1.1 (in compliance
with a charging specification supplementary to the USB2.0 specification).
