With reference to Figure 5.3, it can be seen that IOBUS9-11 and IOBUS16-19 were unused. Figure 5.4
expands upon the previous two figures to detail a fully occupied IOBUS, up to and including IOBUS19.
The gaps at IOBUS9-11 have been filed with 3 GPIO pins, the gaps at IOBUS16-19 have been filled with
the second SPI slave and a further 3 IOBUS pins (17-19) have been allocated to 3 GPIO pins. Note that
GPIO pins A0 and A4 are unused as a sufficient gap wasn't available.
