Power control
Power control
The following is a description of the three available power control modes:
Modes
Power control is available in three modes.
Figure 1.13.5 is the state transition diagram of the above modes.
(a) Normal operation mode
(b) Wait mode
(c) Stop mode
• High-speed mode
• Medium-speed mode
• Low-speed mode
• Low power consumption 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.
Tentative Specifications REV.A
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 oper-
ates 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 f
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
S
becomes the BCLK. The CPU operates according to the fc clock. The fc clock is supplied by the
pecifications in this manual are tentative and subject to change.
