PCINT1, Pin Change Interrupt source 1: The PB1 pin can serve as an external interrupt source.
SS/PCINT0 – 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.
Table 11-7 and Table 11-8 relate the alternate functions of Port B to the overriding signals
shown in Figure 11-5 on page 76. 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..
