SS/PCINT8 – Port B, Bit 0
SS: Slave Port Select input. When the SPI is enabled as a Slave, this pin is configured as an
input regardless of the setting of DDB0. As a Slave, the SPI is activated when this pin is driven
low. When the SPI is enabled as a Master, the data direction of this pin is controlled by DDB0.
When the pin is forced to be an input, the pull-up can still be controlled by the PORTB0 bit
PCINT8, Pin Change Interrupt Source 8: The PB0 pin can serve as an external interrupt source.
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 65. SPI MSTR INPUT and SPI SLAVE OUTPUT constitute the
MISO signal, while MOSI is divided into SPI MSTR OUTPUT and SPI SLAVE INPUT.
