Port B, Bit 1 – MISO/ DO/ OC1A/ PCINT9
DO: Three-wire mode Universal Serial Interface Data output. Three-wire mode Data output
overrides PORTB1 value and it is driven to the port when data direction bit DDB1 is set (one).
PORTB1 still enables the pull-up, if the direction is input and PORTB1 is set (one).
OC1A: Output Compare Match output: The PB1 pin can serve as an external output for the
Timer/Counter1 Compare Match B when configured as an output (DDB1 set). The OC1A pin
is also the output pin for the PWM mode timer function.
PCINT9: Pin Change Interrupt source 9.
Port B, Bit 0 – MOSI/ DI/ SDA/ OC1A/ PCINT8
DI: Data Input in USI Three-wire mode. USI Three-wire mode does not override normal port
functions, so pin must be configure as an input for DI function.
SDA: Two-wire mode Serial Interface Data.
OC1A: Inverted Output Compare Match output: The PB0 pin can serve as an external output
for the Timer/Counter1 Compare Match B when configured as an output (DDB0 set). The
OC1A pin is also the inverted output pin for the PWM mode timer function.
PCINT8: Pin Change Interrupt source 8.
Table 10-7 and Table 10-8 relate the alternate functions of Port B to the overriding signals
Note:
1. “1” when the Fuse is “0” (Programmed).
