DI: Data Input in USI Three-wire mode. USI Three-wire mode does not override normal port
functions, so pin must be configure as an input for DI function.
SDA: Two-wire mode Serial Interface Data.
PCINT0: Pin Change Interrupt source 0.
Table 12-7 and Table 12-8 relate the alternate functions of Port A to the overriding signals
shown in Figure 12-5 on page 61.
