Section 15 Serial Communication Interface (SCI)
15.9
15.9.1
Table 15.12 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.
A TXI interrupt can activate the DTC to perform data transfer. The TDRE flag is cleared to 0
automatically when data is transferred by the DMAC *
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.
An RXI interrupt request can activate the DMAC *
is cleared to 0 automatically when data is transferred by the DMAC *
A TEI interrupt is requested when the TEND flag is set to 1 and the TEIE bit is set to 1. If a TEI
interrupt and a TXI interrupt are requested simultaneously, the TXI interrupt has priority for
acceptance. However, if the TDRE and TEND flags are cleared simultaneously by the TXI
interrupt routine, the SCI cannot branch to the TEI interrupt routine later.
Notes: 1. Supported only by the H8S/2239 Group.

2. The flag is cleared only when DISEL in DTC is 0 with the transfer counter not being 0.
