3.5.2 GPIO Programming
This section describes the usage of GPIOs. AR-B6050 integrated eight bits, 5V TTL
level, bidirectional, and software programmable GPIOs for user’s application. They are all
capable of 5 mA source current for output and 8 mA sink current for input individually. The
electrical characteristics of GPIOs as following table:
PIN SIGNAL PIN SIGNAL
1 GPO0 2 VCC
3 GPO7 4 GPI7
5 GPO2 6 GPI6
7 GPO3 8 GPI5
9 GND 10 GPI4
