CC2650: Bluetooth Smart Keyboard Reference Design Generated Code Question?

Hi,

    I am referring tho the Bluetooth Smart Keyboard Reference Design from this link. http://www.ti.com/tool/TIDC-BLUETOOTH-SMART-KEYBOARD-MODULE

    It has a tool to generate code files. So far I understand how the code works. But, I am not clear how the inPinId2inPinIndex[] array was made. Can the reference to how the inPinId2inPinIndex[] was made be found in one of the technical reference documents? Is it possible to get the code for the code file generator so I know how the array was made? Also, I ported the codes to work for CC2640R2F Launchpad, I would like to know if the array is still applicable to work for CC2640R2F MCU? I have wired a USB Keyboard to CC2640R2F Launchpad to work as BLE HID Keyboard.

// Mapping of Pin Index to Input Pin(Coloumn GPIO)
// Reverse mapping of gInputPinMap
// Invalid Input Pin Index(for pins used as output) are represented as BOARD_INPUTCOUNT.

static const uint8_t inPinId2inPinIndex[MAX_NUM_PINS] =  
{
    BOARD_INPUTCOUNT,
    BOARD_INPUT1,
    BOARD_INPUT4,
    BOARD_INPUT6,
    BOARD_INPUTCOUNT,
    BOARD_INPUT0,
    BOARD_INPUTCOUNT,
    BOARD_INPUTCOUNT,
    BOARD_INPUT15,
    BOARD_INPUT14,
    BOARD_INPUTCOUNT,
    BOARD_INPUT11,
    BOARD_INPUT9,
    BOARD_INPUT16,
    BOARD_INPUT17,
    BOARD_INPUTCOUNT,
    BOARD_INPUTCOUNT,
    BOARD_INPUTCOUNT,
    BOARD_INPUT13,
    BOARD_INPUT12,
    BOARD_INPUT10,
    BOARD_INPUTCOUNT,
    BOARD_INPUT2,
    BOARD_INPUT8,
    BOARD_INPUTCOUNT,
    BOARD_INPUT7,
    BOARD_INPUT5,
    BOARD_INPUT3,
    BOARD_INPUTCOUNT,
    BOARD_INPUTCOUNT,
    BOARD_INPUTCOUNT
};
