6.6 Clearing HALT and SLEEP Modes by Interrupt Causes

A cause of interrupt clears HALT or SLEEP mode to start up the CPU.
The program execution sequence (whether it branches to the interrupt handler routine) after the CPU starts up
depends on the clock status in HALT/SLEEP mode.
See "C.1 Power Saving by Clock Control" in Appendix C for details.
