Section 24 Power-Down Modes

Sleep Instruction Exception Handling
Sleep instruction exception handling is the exception handling initiated by the execution of a
SLEEP instruction. Sleep instruction exception handling is always accepted while the program is
in execution.
When the SLPIE bit is set to 0, the execution of a SLEEP instruction does not initiate sleep
instruction exception handling. Instead, the CPU enters the power-down state. After this,
generation of an exception handling request that cancels the power-down state causes the
powerdown state to be canceled, after which the CPU starts to handle the exception. When the
SLPIE bit is set to 1, sleep instruction exception handling starts after the execution of a SLEEP
instruction. Transitions to the power-down state are inhibited when sleep instruction exception
handling is initiated, and the CPU immediately starts sleep instruction exception handling.
When a SLEEP instruction is executed while the SLPIE bit is cleared to 0, a transition is made to
the power-down state. The power-down state is canceled by a canceling factor interrupt (see figure
24.10).
When a canceling factor interrupt is generated immediately before the execution of a SLEEP
instruction, exception handling for the interrupt starts. When execution returns from the exception
service routine, the SLEEP instruction is executed to enter the power-down state. In this case, the
power-down state is not canceled until the next canceling factor interrupt is generated (see figure
24.11).
When the SLPIE bit is set to 1 in the service routine for a canceling factor interrupt so that the
execution of a SLEEP instruction will produce sleep instruction exception handling, the operation
of the system is as shown in figure 24.12. Even if a canceling factor interrupt is generated
immediately before the SLEEP instruction is executed, sleep instruction exception handling is
initiated by execution of the SLEEP instruction. Therefore, the CPU executes the instruction that
follows the SLEEP instruction after sleep instruction exception and exception service routine
without shifting to the power-down state.
When the SLPIE bit is set to 1 to start sleep exception handling, clear the SSBY bit in SBYCR to
0.
