16.4.11 Interrupt Sources
This module has interrupt sources of receive buffer full, transmit buffer empty, mode fault, and
overrun. In addition, the direct memory access controller can be activated by the receive buffer
full or transmit buffer empty interrupt for data transfer.
Table 16.11 shows the interrupt sources.
When any of the interrupt conditions in table 16.11 is met, an interrupt is generated. The interrupt
sources should be cleared with data transfer by the CPU or direct memory access controller.
