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. In Texas Instruments SLAS655G Document [Page 7] has a pin diagram showing the physical location of where each pin is physically located. 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.
