16.3.14 Interrupts
The interrupts generated by the I²C module are combined into one interrupt vector, I2C_INT. If I²C
interrupts are enabled, an interrupt will be made if one or more of the interrupt flags in I2Cn_IF and their
corresponding bits in I2Cn_IEN are set.
16.3.15 Wake-up
The I²C receive section can be active all the way down to energy mode EM3, and can wake up the CPU
on address interrupt. All address match modes are supported.
