If the generation conditions in Table 26.3 are met, an interrupt request of the synchronous serial communication
unit is generated. Set each interrupt source to 0 by the synchronous serial communication unit interrupt routine.
However, bits TDRE and TEND are automatically set to 0 by writing transmit data to the SSTDR register and the
RDRF bit is automatically set to 0 by reading the SSRDR register. In particular, the TDRE bit is set to 1 (data
transferred from registers SSTDR to SSTRSR) at the same time transmit data is written to the SSTDR register. If
the TDRE bit is further set to 0 (data not transferred from registers SSTDR to SSTRSR), additional 1 byte may be
transmitted.
The synchronous serial communication unit has five interrupt requests: transmit data empty, transmit end,
receive data full, overrun error, and conflict error. Since these interrupt requests are assigned to the synchronous
serial communication unit interrupt vector table, determining interrupt sources by flags is required.
Table 26.3 shows the Interrupt Requests of Synchronous Serial Communication Unit.
