I think there is no way to close watchdog on S12G DataSheet, can you tell me to close watchdog on S12G128?thank you

Hi @ZhaozhangChen,

Yes, it can be disabled this way.

Please note that this is a write-once register in Normal mode.

The register is loaded from the Flash IFR (FOPT) during the reset sequence.

A constant can be place at the IFR.

E.g.

//set FOPT = 0xFF (at 0xFF0E) and FSEC = 0xFE (at 0xFF0F)
//place the constant at address 0xFF08
const unsigned char flash_array[] @@0xFF08= {0xFF,0xFF,0xFF,0xFF,0xFF,0xFF,0xFF,0xFE}

Regards,

Daniel

Can we close watchdog if we set CR0, CR1, CR2 to 0?
