Alternate Functions of Port C
74
AT90CAN128
the MISO signal, while MOSI is divided into SPI MSTR OUTPUT and SPI SLAVE
INPUT.
Table 33 and Table 34 relates the alternate functions of Port B to the overriding signals
shown in Figure 33 on page 68.
Table 33. Overriding Signals for Alternate Functions in PB7..PB4
Note:
Table 34. Overriding Signals for Alternate Functions in PB3..PB0
The Port C has an alternate function as the address high byte for the External Memory
Interface.
