14.4
The SCI has four interrupt sources transmit-end (TEI), receive-error (ERI), receive-data-full
(RXI), and transmit-data-empty (TXI). Table 14.13 lists the interrupt sources and indicates their
priority. These interrupts can be enabled and disabled by the TIE, RIE, and TEIE bits in the serial
control register (SCSCR). Each interrupt request is sent separately to the interrupt controller.
TXI is requested when the TDRE bit in SCSSR is set to 1.
RXI is requested when the RDRF bit in SCSSR is set to 1.
ERI is requested when the ORER, PER, or FER bit in SCSSR is set to 1.
TEI is requested when the TEND bit in SCSSR is set to 1. Where the TXI interrupt indicates that
transmit data writing is enabled, the TEI interrupt indicates that the transmit operation is complete.
