// Function Name: bootloadGpioInit
// Description: This function selects the chip's GPIO configuration. These
// settings are the minimum base configuration needed to
// support the bootloader functionality. These settings can
// be modified for custom applications as long as the base
// settings are preserved.
// Parameters: none
// Returns: none
