It can be driven low to provide a reset signal out to the external components Conversely it can be asserted low from the outside to reset the microcontroller Core and the peripherals The NRST pin integrates a permanent pull up resistor of 100 to VDDIO On the SAM4E EK board the NRST signal is connected to the LCD module and JTAG port Note At power on the NRST signal is asserted with default duration of two clock cycles That duration may not be sufficient to correctly reset any other system or board devices connected to that signal First in your custom application you need to check for these device s datasheets about reset duration requirements Then you need to set an appropriate configuration in the NRST Manager This is done through the ERSTL field in the RSTC_MR register The NRST duration is thereby configurable between 60us 2s whether it is subsequently activated by a software reset or a user reset Refer to the SAM4E16 datasheet for in depth information Atmel SAM4E EK User Guide 10 42067 5 4 04 2013 4 3 5 Power supply and management The Atmel SAM4E EK board is supplied with an external 5V DC block through input J1 It is protected by a PolyZen diode MN2 and an LC combinatory filter MN3 The PolyZen is used in the event of an incorrect power supply connection The adjustable LDO regulator MN4 is used for the 3 3V rail main supply It powers all the 3 3V components on the board Figure 4 4 Powe
