TG functionality can be enabled by populating R25 and R29 with 0 O resistors These resistors connect the USB ID and USB Veus signals to PBO and PB1 When these resistors are populated PBO and PB1 must remain in the respective USB pin mode configurations to prevent device damage PBO and PB1 are also present on the J1 BoosterPack header Therefore if R25 or R29 are populated care must be taken not to conflict these signals with BoosterPack signals USB embedded host operation can be enabled in the same way for USB devices that are self powered Providing power when acting as a USB host requires a BoosterPack with power switching and appropriate connectors All USB host signals are available on the BoosterPack interface except D and D which are only available on the USB micro A B connector and the two adjacent test points When connected as a USB device the evaluation board can be powered from either the ICDI or the USB Device connectors The user can select the power source by moving the POWER SELECT switch SW3 to the Device position See the Power Management schematic appended to this document 2 1 3 Motion Control The EK TM4C123GXL includes the Tiva C Series Motion Control PWM technology featuring two PWM modules capable of generating 16 PWM outputs Each PWM module provides a great deal of flexibility and can generate simple PWM signals for example those required by a simple charge pump as well as paired PWM signals with dead band
