• AIN1/PCINT1 – Port B, Bit 1
AIN1: Analog Comparator Negative input and ADC6: ADC input channel 6
the port pin as input with the internal pull-up switched off to avoid the digital port function
from interfering with the function of the analog comparator or analog to digital converter.
PCINT1: Pin Change Interrupt Source 1. The PB1 pin can serve as an external interrupt
source.
• AIN0/PCINT0 – Port B, Bit 0
AIN0: Analog Comparator Positive input and ADC5: ADC input channel 5
port pin as input with the internal pull-up switched off to avoid the digital port function
from interfering with the function of the Analog Comparator or analog to digital
converter.
PCINT0: Pin Change Interrupt Source 0. The PB0 pin can serve as an external interrupt
source.
Table 27 and Table 28 relate the alternate functions of Port B to the overriding signals
shown in Figure 25 on page 51. SPI MSTR INPUT and SPI SLAVE OUTPUT constitute
the MISO signal, while MOSI is divided into SPI MSTR OUTPUT and SPI SLAVE
INPUT.
