ATmega640/V-1280/V-1281/V-2560/V-2561/V [DATASHEET]
DS40002211A
Table 13-7 and Table 13-8 relate the alternate functions of Port B to the overriding signals shown in Figure 13-5 on
page 73. SPI MSTR INPUT and SPI SLAVE OUTPUT constitute the MISO signal, while MOSI is divided into SPI
MSTR OUTPUT and SPI SLAVE INPUT.
PCINT0, Pin Change Interrupt source 0: The PB0 pin can serve as an external interrupt source.
