When connecting the MCU to the programmer via the JTAG interface, it is possible for a local power supply connected to the MCU to be used or for power from the debugging/programming adapter to be used. Since having power supplied to the MCU from the debugging/programming adapter can be useful for use outside of the Sunseeker vehicle, we chose to use that.\hypertarget{design_choices_autotoc_md3}{}\doxysubsection{Microcontroller Peripheral Connections}\label{design_choices_autotoc_md3}

The thinking behind this so far, is to try and balance the load between the modules with SPI protocol being used in more high data-\/rate peripherals and I2C used with lower or less-\/used peripherals. \hypertarget{deviceSpecifications}{}\doxysection{Device Specifications}\label{deviceSpecifications}

In addition to trying to keep the MCU and PCB organized with the left-\/side being to do with the Sunseeker vehicle and the right side to be peripherals interacting with users, we tried to also load-\/balance the USCI modules, as well as have the SPI protocol be used in more high data-\/rate peripherals and I2C used with lower or less-\/used peripherals.
