GPIO & Delay Time Setting

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 Data Value
