Gpio & Delay Time Setting; Gpio And Ignition Control Register - JHCTech FEBC-3150 User Manual

Power Management
Power‐off delay time is select-able by Software to disable and enable in 0‐255 minutes
Ignition On/Off status detectable by SW
If the ignition is off and the system is still on after 3 Sec, IVC‐3150 will shut

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.
