Section 17 Serial Communication Interface (SCI)
17.4
The SCI has four interrupt sources in each channel: Transmit-end (TEI), receive-error (ERI),
receive-data-full (RXI), and transmit-data-empty (TXI). Table 17.13 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 the SCSSR is set to 1.
RXI is requested when the RDRF bit in the SCSSR is set to 1.
ERI is requested when the ORER, PER, or FER bit in the SCSSR is set to 1.
TEI is requested when the TEND bit in the 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.
