AT91SAM9G20 Summary
– Three external clock inputs
– Five internal clock inputs
– Two multi-purpose input/output signals
Each block contains two global registers that act on all three TC Channels
Note:
TC Block 0 (TC0, TC1, TC2) and TC Block 1 (TC3, TC4, TC5) have identical user interfaces. See
Figure 8-1, “AT91SAM9G20 Memory Mapping,” on page 19 for TC Block 0 and TC Block 1 base
addresses.
