5.2 GPIO & Delay Time Setting
5.2.1 GPIO and Ignition Control Register
The General Purpose I/O is an interface available on some devices. These can read
digital signals from other parts of a circuit, or output to control other devices. At GPIO
control register, the GPI is use to receive data, the GPO is set data to send.
I/O port: 0xA35 (base address) for Control Register (Read 0xA2h / Write 0xA1h)
0xA36 (base address) for Control Data Value
