• DI/SDA/PCINT5 - Port B, Bit 5
DI: Three-wire mode Universal Serial Interface Data input. Three-wire mode does not override
normal port functions, so pin must be configured as an input. SDA: Two-wire mode Serial Inter-
face Data.
PCINT5: Pin Change Interrupt Source 5. The PB5 pin can serve as an external interrupt source.
• OC1B/PCINT4 – Port B, Bit 4
OC1B: Output Compare Match B output: The PB4 pin can serve as an external output for the
Timer/Counter1 Output Compare B. The pin has to be configured as an output (DDB4 set (one))
to serve this function. The OC1B pin is also the output pin for the PWM mode timer function.
PCINT4: Pin Change Interrupt Source 4. The PB4 pin can serve as an external interrupt source.
• OC1A/PCINT3 – Port B, Bit 3
OC1A: Output Compare Match A output: The PB3 pin can serve as an external output for the
Timer/Counter1 Output Compare A. The pin has to be configured as an output (DDB3 set (one))
to serve this function. The OC1A pin is also the output pin for the PWM mode timer function.
PCINT3: Pin Change Interrupt Source 3: The PB3 pin can serve as an external interrupt source.
• OC0A/PCINT2 – Port B, Bit 2
OC0A: Output Compare Match A output. The PB2 pin can serve as an external output for the
Timer/Counter0 Output Compare A. The pin has to be configured as an output (DDB2 set (one))
to serve this function. The OC0A pin is also the output pin for the PWM mode timer function.
PCINT2: Pin Change Interrupt Source 2. The PB2 pin can serve as an external interrupt source.
• AIN1/PCINT1 – Port B, Bit 1
AIN1: Analog Comparator Negative input
Configure 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.
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. Configure 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.
PCINT0: Pin Change Interrupt Source 0. The PB0 pin can serve as an external interrupt source.
Table 26
and
Table 27
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.
