Port 1 is controlled by SFR-registers 0x90, 0x96 and 0x97, and only the 4 lower bits of
the registers are used.

Direction for each bit of Port 1
0: Output, 1: Input
Direction is overridden if alternate function is selected
for a pin, or if SPI_CTRL=01.
SPI_MISO is always input.
Select alternate functions for each pin of P1

P1 is by default configured as a SPI master port. In this case, it is then controlled by the
3 SFR registers 0xB2, 0xB3 and 0xB4 as shown in Table 33 on page 43.
