Setting Up the AT91EB42 Evaluation Board 2.4 Jumper Settings JP1 is used to boot standard or user programs. For standard operations, set it in the STD position. JP8 is used to select the core power supply of the AT91M42800: 3.3V or 1.8V. For oper- ation at 1.8V, MCK frequency shall be limited to 17 MHz. For more information about jumpers and other straps, see Section 5. 2.5 Powering Up DC power is supplied to the board via the 2.1 mm socket (J1) shown in Figure 2-2. The polarity of the power sup

Section 4 Circuit Description 4.1 AT91M42800 Figure 6-1 on page 6-2 shows the AT91M42800. The footprint is for a 144-pin TQFP package. Processor Strap CB20 enables the user to choose between the standard ICE debug mode and the JTAG boundary scan mode of operation. The operating mode is defined by the state of the JTAGSEL input detected at reset. Jumper JP5 (see Figure 6-8 on page 6-9 in Section 6, “Appendix B – Schematics”) can be removed by the user to allow measurement of the current demand

Circuit Description of watchdog time-out as the pin NWDOVF of the AT91M42800 is connected to its input MR. The assertion of this reset signal will light up the red RESET LED (D10). By pressing the CLEAR RESET push button (S1), the LED can be turned off. Another supervisory circuit initializes separately the microcontroller-embedded JTAG/ICE interface when the 3.3V supply voltage drops below 3.0V. Note that this volt- age can be changed, depending on the board production series. These separated r

Section 5 Appendix A – Configuration Straps 5.1 Configuration By adding the I/O and EBI expansion connectors, users can connect their own peripher- als to the evaluation board. These peripherals may require more I/O lines than available Straps (CB1 - 23, while the board is in its default state. Extra I/O lines can be made available by disabling JP1 - 8) some of the on-board peripherals or features. This is done using the configuration straps detailed below. Some of these straps present a defaul
