Alternate Functions Of
Port B
1477K–AVR–08/10
Port B has an alternate functions for the ADC, Clocking, Timer/Counters, USI, SPI programming
and pin change interrupt. The ADC is described in “Analog to Digital Converter” on page 94,
Clocking in “AVR CPU Core” on page 7, timers in “Timer/Counters” on page 64 and USI in “Uni-
versal Serial Interface – USI” on page 80. Pin change interrupt triggers on pins PB7 - PB0 if
interrupt is enabled and it is not masked by the alternate functions even if the pin is configured
as an output. See details from “Pin Change Interrupt” on page 62. Pin functions in programming
modes are described in “Memory Programming” on page 107. The alternate functions are shown
in Table 26.
Table 26. Port B Pins Alternate Functions
The alternate pin configuration is as follows:
• ADC10/RESET/PCINT1 – Port B, Bit 7
ADC10: ADC Input Channel 10. Configure the port pins as inputs with the internal pull-ups
switched off to avoid the digital port function from interfering with the function of the analog to
digital converter.
RESET: External Reset input is active low and enabled by unprogramming (“1”) the RSTDISBL
Fuse. Pullup is activated and output driver and digital input are deactivated when the pin is used
as the RESET pin.
PCINT1: Pin Change Interrupt 1 pin. Pin change interrupt is enabled on pin when global interrupt
is enabled, pin change interrupt is enabled and the alternate function do not mask the interrupt.
