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.

When interrupt conditions shown in table 16.2 are satisfied and the I bit in CCR is 0, the CPU
executes interrupt exception processing. Clear each interrupt source in the exception processing.
16.6 Usage
Note
16.6.1
Setting of Module Stop Mode
The SSU can be enabled/disabled by the module stop control register setting and is disabled by the
initial value. Canceling module stop mode enables to access the SSU registers. For details, see
section 21, Power-Down Modes.
