Fignition's Firmware Overview - FIGnition FUZE Hardware Reference Manual

• Timer 0 is fully available for user applications and timer 1's OCRB and timer 2's OCRB
registers can be used too (though the timer configurations themselves can't be changed
without disrupting video).
• The analog comparator and the A/D circuitry can be used to a limited degree since AIN0
on pin has limited availability and the ADC channels 4 and 5 can be used.
• The I2C (also called TWI) unit can be used.
