Okay so I noticed last night while building a circuitboard that the TLC5940 Grayscale clock (for the PWM function) is connected to the INT1 pin when set-up with an ATmega328p. When connecting it up like that on the 32U4, I noticeced the INT1 pin is also the SDA pin (for I2C/TWI). Unfortunatly my project requires the I2C bus for a different IC.
Can I change the grayscale pin for this to another pin and will still work?
