In addition to the normal program execution state, this LSI has power-down modes in which
operation of the CPU and oscillator is halted and power consumption is reduced. Low-power
operation can be achieved by individually controlling the CPU, on-chip peripheral modules, and
so on.
This LSI's operating modes are as follows:
(1) High-speed mode
(2) Medium-speed mode
(3) Sleep mode
(4) Watch mode
(5) Module stop mode
(6) Software standby mode
(7) Hardware standby mode
Of these, (2) to (7) are power-down modes. Sleep mode is a CPU state, medium-speed mode is
CPU and bus master states, and module stop mode is an on-chip peripheral function (including bus
masters other than the CPU) state.
After a reset, the LSI is in high-speed mode.
Table 22.1 shows the internal state of the LSI in the respective modes. Table 22.2 shows the
conditions for shifting between power-down modes.
Figure 22.1 is a mode transition diagram.
