Power control
Rev.2.00
REJ03B0005-0200
The following is a description of the three available power control modes. Figure 1.22 shows the state transition diagram
for these modes.
Normal operation mode
Wait mode
Stop mode
• High-speed mode
• Medium-speed mode
• Low-speed mode
• Low power consumption mode
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.
fc becomes the BCLK. The CPU operates according to the fc clock. The fc clock is supplied by the 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 subclock selected as the
count source.
The CPU operation is stopped. The oscillators do not stop.
All oscillators stop. The CPU and all built-in peripheral functions stop. Of the three modes discusses, the stop mode is
the most effective in decreasing power consumption.
