The programmed board power consumption is about 50 mA. RESET CIRCUIT: SAM3-H256 reset circuit includes U1 (MCP130T), R12 (10k), JTAG connector pin 15, EXT2 pin 20, ATSAM3S4BA-AU pin 39 (NRST) and RESET button. CLOCK CIRCUIT: Quartz crystal Q1 12.000 MHz is connected to ATSAM3S4BA-AU pin 61 (PB8/XOUT) and pin 62 (PB9/XIN). JUMPER DESCRIPTION: L_E This jumper, when closed, enables status led – STAT. Default state is closed. TEST This jumper, when closed, connects ATSAM3S4BA-AU pin 40 (TST) to 3.3V. The TST pin is used for JTAG Boundary Scan Manufacturing Test or Fast Flash programming mode. When TEST jumper is opened – normal mode is enabled. Default state is opened. Page 9 Description for programming via USB port using SAM-BA software The ATSAM3S4BA-AU can be programmed via USB using the SAM-BATM software. Before being able to use SAM-BA, a recovery procedure, which consists of copying the SAM-BA Boot Assistant into Flash must be performed as follows: 1. Disconnect board from USB 2. Connect PB12 to 3.3V 3. Power up the board 4. Wait 10s 5. Power down the board 6. Remove the connection between PB12 and 3.3V 7. Power up the board via USB 8. If SAM-BA USB driver are installed you can use SAM-BA tool INPUT/OUTPUT: Status Led (green) with name STAT connected via jumper L_E to ATSAM3S4BAAU pin 31 (PA8/CTS0/ADTRG/WKUP5/XOUT32). Power-on LED (red) with name PWR – this LED shows that +3.3V is applied to the board. Reset button with name RESET connected to ATSAM3S4BA-AU pin 39 (NRST). Page 10 EXTERNAL CONNECTORS DESCRIPTION: JTAG: The JTAG connector allows the software debugger to talk via a JTAG (Joint Test Action Group) port directly to the core. Instructions may be inserted and executed by the core thus allowing ATSAM3S4BA-AU memory to be programmed with code and executed step by step by the host software. For more details refer to IEEE Standard 1149.1 - 1990 Standard Test Access Port and Boundary Scan Architecture and ATSAM3S4BA-AU datasheets and users manual.
