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 Register (Read 0xA2h / Write 0xA1h) 0xA36 (base address)
for Control Data Value
