11.5.1
Table 11.7 shows the interrupt sources in normal serial communication interface mode. A different
interrupt vector is assigned to each interrupt source, and individual interrupt sources can be
enabled or disabled using the enable bits in SCR.
When the TDRE flag in SSR is set to 1, a TXI interrupt request is generated. When the TEND flag
in SSR is set to 1, a TEI interrupt request is generated.
When the RDRF flag in SSR is set to 1, an RXI interrupt request is generated. When the ORER,
PER, or FER flag in SSR is set to 1, an ERI interrupt request is generated. A TEI interrupt is
generated when the TEND flag is set to 1 while the TEIE bit is set to 1. If a TEI interrupt and a
TXI interrupt are generated simultaneously, the TXI interrupt has priority for acceptance.
However, note that if the TDRE and TEND flags are cleared simultaneously by the TXI interrupt
routine, the SCI cannot branch to the TEI interrupt routine later.
