2.5.8 Power Control
The following is a description of the three available power control modes:
Modes
Power control is available in three modes.
Figure 2.5.7 is the state transition diagram of the above modes.
(1) Normal operation mode
(2) Wait mode
(3) Stop mode
The CPU operation is stopped. The oscillators do not stop.
All oscillators stop. The CPU and all built-in peripheral functions stop. This mode, among the three
modes listed here, is the most effective in decreasing power consumption.
Divide-by-1 frequency of the main clock becomes the BCLK. The CPU operates with the internal
clock selected. Each peripheral function operates according to its assigned clock.
Divide-by-2, divide-by-4, divide-by-8, or divide-by-16 frequency of the main clock becomes the
BCLK. The CPU operates according to the internal clock selected. Each peripheral function operates
according to its assigned clock.
f
secondary clock. Each peripheral function operates according to its assigned clock.
The main clock operating in low-speed mode is stopped. The CPU operates according to the fc
clock. The fc clock is supplied by the secondary clock. The only peripheral functions that operate are
those with the sub-clock selected as the count source.
C
High-speed mode
Medium-speed mode
Low-speed mode
Low power consumption mode
becomes the BCLK. The CPU operates according to the fc clock. The fc clock is supplied by the
