F71869A  
5.10 Scan Code Function  
F71869A has 8 GPIO pins (GPIO 35~37, GPIO 50~54) support scan code. These pins can not  
only be set to volume up/down, mute and PWM up/down but also any function keys on keyboard.  
Because the protocol for these 5 pins is scan code, so we don’t need a driver to connect this  
function to OS. If the button for the GPIO has been pressed continuesly over nearly 1 second  
(delay time), the GPIO will repeatedly sending this function in an interval of 50 ms (repeat time).  
The delay time could be set from 0.5 to 1.5 sec. The repeat time could be set from 50, 100, 250 to  
500 ms.  
5.11 Over Voltage Protection  
F71869A over voltage protection function could protect the damage from voltage spikes via  
over voltage protection (OVP) function. Voltage protection function is enabled via setting the  
related register. When force mode occurs, the system would shut down and then can not boot at  
all. Only re-plugging the power code (cut off VSB) could re-activate or re-boot the system at the  
force mode. Please see below table for detail information:
