4.1.1 'Gaid' - Return to Normal Operation

Table 4-1 'Gaid' - Return to Normal Operation
DescriptionThe 'Gaid' Task causes a warm restart of the PD Controller processor.
INPUT DATAXNone
OUTPUT DATAXNone
Task CompletionTechnically this Task never completes because the processor restarts. However, because all HI registers return to their default state upon reboot, all CMDx/DATAx registers will return to 0, which will mark this Task as complete.
Side EffectsThe 'Gaid' Task causes a warm restart of the PD Controller processor. PD Controller can momentarily NAK I2C transactions while rebooting.
Additional InformationThe PD controller is in the 'APP ' mode, then it immediately goes to the Error Recovery state then after delaying 1 second (typical) it does a warm restart.
