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

Target: Reload Timer Initial Value to TCO_RLD Register (Offset 0x00)

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

Step4 Start to Count

Step1: WordData = ReadIOWord(0x468) //0x460+0x08

Step2: WordData = WordData & 0xF7FF //Enabled to count

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