CHAPTER 6 LOW-POWER CONSUMPTION MODE
6.3
Low-Power Consumption Mode Control Register (LPMCR)
The low-power consumption mode control register (LPMCR) performs functions
including changing the current mode to the low-power consumption mode, canceling
from the low-power consumption mode, and specifying the number of CPU-clock
pause cycles in the CPU intermittent operation mode.

16 cycles (CPU clock: Resource clock =
1: About 5 to 6)
32 cycles (CPU clock: Resource clock =
1: About 9 to 10)
