The I C module is operated with an internal approximately 12-MHz clock

The noise filter suppresses any noise that is 50 ns or less. It is designed to
suppress noise with 1 ICLK, assuming the lower and upper limits of ICLK are
8 MHz and 16 MHz, respectively.

The I C module generates six types of interrupts: Arbitration-lost,
no-acknowledge, general call, registers-ready-for-access, receive, and
transmit. These six interrupts are accompanied by six interrupt masks and
flags defined in the I2C_IE and I2C_STAT registers, respectively.
