Port B Schematics
0841G–09/01
• AIN0 – Port B, Bit 2
AIN0: Analog Comparator Positive Input. When configured as an input (DDB2 is cleared
[zero]) and with the internal MOS pull-up resistor switched off (PB2 is cleared [zero]),
this pin also serves as the positive input of the On-chip Analog Comparator.
• T1 – Port B, Bit 1
T1: Timer/Counter1 counter source. See the timer description for further details
• T0 – Port B, Bit 0
T0: Timer/Counter0 counter source. See the timer description for further details.
Note that all port pins are synchronized. The synchronization latches are, however, not
shown in the figures.
