    Section 3 Hardware Description The AT43DK370 development board comes pre-configured as a USB Host in StandAl- one (Flash) mode. Alternative settings are available through jumper configurations. Complete descriptions of the jumper settings are explained in Section 3.1. Figure 3-1. AT43USB370 Development Board Components Layout...

  • Page 14: Jumper Settings

    The AT43DK370 Development Board supports two modes of operation, the default Standalone (or Flash) Mode and the ICE (In-Circuit Emulator) mode. In Standalone Mode, the AT43DK370 Development Board executes code from its on board flash ROM. While in ICE Mode, an In-Circuit Emulator for the ARM processor can be con- nected through J4 to further facilitate code development.
