Signal Descriptions
I
2
C is a two-wire bus for inter-IC communication. Data and clock signals carry
information between the connected devices. The following is the I
2
C Interface. The SoC
supports 7 I
2
C interfaces for general purpose to control external devices. The I
2
C
signals are muxed over GPIOs.
