38.11.3 Main Interrupts
The CxINT register contains all the main interrupts. The following interrupts are a logical ‘OR’ of all combined FIFO interrupts: RXIF, TXIF, RXOVIF and TXATIF. These flags are read-only and must be cleared in preceding hierarchies.
The TEFIF is generated in the TEF. This flag is read-only and must be cleared in preceding hierarchies.
All interrupts in CxINT can be enabled individually.
