8. POWER SAVE FUNCTION
The V850ES/SA2 and V850ES/SA3 have the following power save functions to realize an effective low-power-
consuming system.
{
{
{
{
HALT mode:
IDLE mode:
STOP mode:
Backup mode:
Only the clock of the CPU is stopped in this mode.
All operations on the chip other than oscillator operation are stopped in this mode.
All operations on the chip other than subclock oscillator operation are stopped in this mode.
The power supply other than for the subclock oscillator, real-time counter, and internal
RAM can be disconnected.
The following table shows the operating states of the on-chip peripheral functions in each mode.
