Step2 Set Initial Value into Timer Register
Target: Set TCO Timer Initial Value (Offset 0x12)
Step1: WordData = ReadIOWord(0x472) //0x460+0x12
Step2: WordData = Set Bit[9:0] //0x000~0xFFF. 1 ticks = 0.6s
Step3: WriteIOWord(0x472,WordData) //Write back to IO
Example:
If you want to reboot after 5 seconds, you should set WordData to 0x05.
5 - 2 = 3
//5 minus system’s default 2 seconds leaves the real setting
data.
3 / 0.6 = 5 //5 ticks

Step1: WriteIOWord(0x460, 0x01) //Reload Timer

Step3: WriteIOWord(0x468, WordData) // Write back to IO
