Interrupt Requests
The SSU interrupt requests consist of transmit data register empty, transmit end, receive data
register full, overrun error, and conflict error. Of these interrupt sources, transmit data register
empty, transmit end, receive data register full can activate the DTC for data transfer.
The TDRE, TEND, and RDRF bits are automatically cleared to 0 by the DTC data transfer. Since
these interrupt requests are allocated to four vector addresses: SSEr_i0, SSRx_i0, SSTx_i0 and
SSERT_i1, the interrupt sources must be distinguished by flags. Table 16.2 lists interrupt sources.
