TPS65987DDJ: HRESET behavior

Roy Hsu

Part Number: TPS65987DDJ

Hi Team,

What's the HRESET behavior of this device? Datasheet says it "reinitialize" all device settings. Does that mean bringing every register setting to the default values or re-loading settings from external flash?

Thanks !

HRESET doesn't reloading setting from flash. It is equivalent to softreset where processor resets and continues and if there is valid image loaded in RAM already it will just use that and not reload it.

Hi Ghouse,

Thanks for the response! Is there any other way that we can force the 987D to re-load settings from external flash without power-cycling the device? Can I use "PTCs" to achieve this?

Thanks!

You can use GAID 4CC command to achieve this. You should be able to find this command in the Host Interface TRM
