Section 4 Exception Handling
4.7.2
The sleep instruction exception handling starts when a sleep instruction is executed with the SSBY
bit in SBYCR set to 0 and the SLPIE bit in SBYCR set to 1. The sleep instruction exception
handling can always be executed in the program execution state. In the exception handling, the
CPU operates as follows.
1. The contents of PC, CCR, and EXR are saved in the stack.
2. The interrupt mask bit is updated and the T bit is cleared to 0.
3. An exception handling vector table address corresponding to the vector number specified in
Bus masters other than the CPU may gain the bus mastership after a sleep instruction has been
executed. In such cases, the sleep instruction will be started when the transactions of a bus master
other than the CPU has been completed and the CPU has gained the bus mastership.
Table 4.9 shows the state of CCR and EXR after execution of sleep instruction exception
handling. For details, see section 20.9, Sleep Instruction Exception Handling.

from the vector table to PC, and program execution starts from that address.
