Section 12 Serial Communication Interface
12.4
The SCI has four interrupt request sources: transmit-end interrupt (TEI), receive-error (ERI),
receive-data-full (RXI), and transmit-data-empty interrupt (TXI). Table 12.12 lists the interrupt
sources and indicates their priority. These interrupts can be enabled or disabled by the TIE, RIE,
and TEIE bits in SCR. Each interrupt request is sent separately to the interrupt controller.
A TXI interrupt is requested when the TDRE flag is set to 1 in SSR. A TEI interrupt is requested
when the TEND flag is set to 1 in SSR.
An RXI interrupt is requested when the RDRF flag is set to 1 in SSR. An ERI interrupt is
requested when the ORER, PER, or FER flag is set to 1 in SSR.
