23B.4 Sleep Mode
23B.4.1 Sleep Mode
When the SLEEP instruction is executed when the SBYCR SSBY bit = 0 and the LPWRCR
LSON bit = 0, the CPU enters the sleep mode. In sleep mode, CPU operation stops but the
contents of the CPUís internal registers are retained. Other supporting modules do not stop.
23B.4.2 Exiting Sleep Mode
Sleep mode is exited by any interrupt, or signals at the
Exiting Sleep Mode by Interrupts: When an interrupt occurs, sleep mode is exited and interrupt
exception processing starts. Sleep mode is not exited if the interrupt is disabled, or interrupts other
than NMI are masked by the CPU.
