Overview of the TWI Module
SCL and SDA Pins
The TWI module is comprised of several submodules, as shown in
drawn in a thick line are accessible through the AVR
Figure 6-85. Overview of the TWI Module
These pins interface the AVR TWI with the rest of the MCU system. The output drivers contain
a slew-rate limiter in order to conform to the TWI specification. The input stages contain a
spike suppression unit removing spikes shorter than 50 ns. Note that the internal pull-ups in
the AVR pads can be enabled by setting the PORT bits corresponding to the SCL and SDA
pins, as explained in the I/O Port section. The internal pull-ups can in some systems eliminate
the need for external ones.
