Page 13: Chapter 2: Hardware Description
Microcontroller, Reset, GPIO Pads, and JTAG (Schematic page 1) Microcontroller The evaluation board uses the Stellaris EK-LM3S9B92 microcontroller. A 16 MHz crystal provides the main oscillator clock which can directly drive the ARM core clock or can drive an internal PLL to increase the core clock up to 80 MHz. -
Page 14: Figure 2-2. Gpio Pads
Hardware Description Reset A reset switch and R-C network connects to the microcontroller’s RSTn input. The reset signal is also connected to the JTAG/SWD connector J1 to allow reset control from the debugger. GPIO Pads Four groups of oversized board pads with a 0.1” spacing provide access to GPIO signals and standard 0.1”... -
Page 15: Figure 2-4. Pwr/Uart Connector
Stellaris® LM3S9B92 Evaluation Kit User’s Manual PWR/UART The PWR/UART connector J2 is used to provide 5 V power from the ICDI board and also to connect the LM3S9B92 UART0 signals. This is a 2x4 fine pitch (0.050") connector, see (Figure 2-4) for signal definition. The UART0 signals are connected to GPIO jumpers JR1 and JR2 and can be disconnected from connector J2 if required, see “GPIO Jumpers”... -
Page 16: In-Circuit Debug Interface Board
Hardware Description In-Circuit Debug Interface Board The ICDI board is used to download and debug programs on the EK-LM3S9B92 evaluation board, but can also be used for debug of other Luminary Micro boards. A block diagram is shown in Figure 2-5. Figure 2-5. -
Page 17: Figure 2-6. Jtag/Swd Connector J1
Stellaris® LM3S9B92 Evaluation Kit User’s Manual fine pitch connector, including the EK-LM3S9B92. The signal direction shown for J1 and J3 applies when the ICDI is used as the JTAG/SWD debugger and LED D2 (DEBUG ACTIVE) is lit on. In this case only one of the two connectors J1/J3 should be used. - Page 18 Hardware Description JTAG / SWD Multiplexer (Schematic page 2) Buffers A set of tri-state buffers is used to multiplex JTAG and SWD signals, and also multiplex the UART VCP_TX signal with the SWO signal. LED D2 (DEBUG ACTIVE) is lit on when these buffers are enabled.
