A.1 Watchdog Timer Programming
AEC-6637 utilizes ITE IT8728F chipset as its watchdog timer controller.
Below are the procedures to complete its configuration and the AAEON initial
watchdog timer program is also attached based on which you can develop customized
program to fit your application.
Configuring Sequence Description
After the hardware reset or power-on reset, the ITE 8728F enters the normal mode with
all logical devices disabled except KBC. The initial state (enable bit ) of this logical
device (KBC) is determined by the state of pin 121 (DTR1#) at the falling edge of the
system reset during power-on reset.
There are three steps to complete the configuration setup: (1) Enter the MB PnP Mode;
(2) Modify the data of configuration registers; (3) Exit the MB PnP Mode. Undesired
result may occur if the MB PnP Mode is not exited normally.
