Software should not rely on the value of a reserved bit. To provide
compatibility with future products, the value of a reserved bit should be
preserved across a read-modify-write operation.

Receive FIFO Full Raw Interrupt Status
DescriptionValue
No interrupt0
The Receive FIFO Full interrupt is pending.1
This bit is cleared by writing a 1 to the RXFFIC bit in the I2CSICR
register.
0RORXFFRIS8
Transmit FIFO Empty Raw Interrupt Status
DescriptionValue
No interrupt0
The Transmit FIFO Empty interrupt is pending.1
This bit is cleared by writing a 1 to the TXFEIC bit in the I2CSICR
register.
Note that if the TXFERIS interrupt is cleared (by setting the TXFEIC bit)
when the TX FIFO is empty, the TXFERIS interrupt does not reassert
even though the TX FIFO remains empty in this situation.
