F75113
LED Function
F75113 provides 24 pin LED (GPIO0X~GPIO2X) display for system control. The LED blinked by 0.25Hz, 0.5Hz,
1Hz and 2Hz with open drain capability (Default). There is a figure describe how the LEDs will perform.

SMI Function
F75113 provides 7 SMI output pins for system control. Also, SMI can be programming to level mode or pulse
mode. In pulse mode, users can select 200us or 150ms pulse width for SMI output. Then, the SMI can be triggered by
any of the GPIO0X ~ GPIO4X pins.
WatchDog Timer Function
F75113 provides two sets of WatchDog Timers for system reset. The watchdog timer1 timeout unit is set to
second and range is 0 to 127 seconds. When the timeout has occurred, that will generate a active pulse signal or level
signal. There is a figure describe how WatchDog Timer output RSTOUT signal.

The watchdog timer2 timeout unit is set to second or minutes and range is 0 to 255. When the timeout has
occurred, that will generate a active pulse signal or level signal.
