Hi,
When setting "#define CONFIG_RTC_MPC8xx" ,how could I do in my hardware scheme to make it really work?I mean what kind of battery(Capacity and Type) and how to connect it with 8xx?Someone said HW must monitor the power status and before power failed SW could set 8xx into powerdown mode for keeping 8xx RTC still work with battery.Is this so?
Best regards,
Sam
