i have a DUE that runs in a machine with a power supply that takes a little time to get up to voltage. the DUE will not boot reliably when the power is first turned on. it always does the second time when there is probably some voltage in the filter caps.is there any way to insure that the DUE re-boots if it encounters a slow start voltage?
- Embedded voltage regulator for single supply operation- POR, BOD and Watchdog for safe reset
10.2 Power-on-Reset, Brownout and Supply MonitorThe SAM3X/A embeds three features to monitor, warn and/or reset the chip:• Power-on-Reset on VDDBU• Brownout Detector on VDDCORE• Supply Monitor on VDDUTMI10.2.1 Power-on-Reset on VDDBUThe Power-on-Reset monitors VDDBU. It is always activated and monitors voltage at start upbut also during power down. If VDDBU goes below the threshold voltage, the entire chip is reset.For more information, refer to the "Electrical Characteristics" section of the product datasheet.10.2.2 Brownout Detector on VDDCOREThe Brownout Detector monitors VDDCORE. It is active by default. It can be deactivated by softwarethrough the Supply Controller (SUPC_MR). It is especially recommended to disable itduring low-power modes such as wait or sleep modes.If VDDCORE goes below the threshold voltage, the reset of the core is asserted. For more information,refer to the "Supply Controller" and "Electrical Characteristics" sections of the productdatasheet.10.2.3 Supply Monitor on VDDUTMIThe Supply Monitor monitors VDDUTMI. It is not active by default. It can be activated by softwareand is fully programmable with 16 steps for the threshold (between 1.9V to 3.4V). It iscontrolled by the Supply Controller (SUPC). A sample mode is possible. It allows to divide thesupply monitor power consumption by a factor of up to 2048. For more information,
