4.11.8 Interrupt function
This serial interface includes a function that generates the below indicated three types of interrupts.
Transmitting complete interrupt
Receiving complete interrupt
Error interrupt
The interrupt factor flag ISxx and the interrupt mask register EISxx for the respective interrupt factors are
provided and then the interrupt can be disabled/enabled by the software.
Figure 4.11.8.1 shows the configuration of the serial interface interrupt circuit.
