HD404369 Series

Standby Mode: In standby mode, the oscillators continue to operate, but the clocks related to instruction

execution stop. Therefore, the CPU operation stops, but all RAM and register contents are retained, and the

D or R port status, when set to output, is maintained. Peripheral functions such as interrupts, timers, and

serial interface continue to operate. The power dissipation in this mode is lower than in active mode

because the CPU stops.

The MCU enters standby mode when the SBY instruction is executed in active mode.

Standby mode is terminated by a

RESET input or an interrupt request. If it is terminated by RESET input,

the MCU is reset as well. After an interrupt request, the MCU enters active mode and executes the next

instruction after the SBY instruction. If the interrupt enable flag is 1, the interrupt is then processed; if it is

0, the interrupt request is left pending and normal instruction execution continues. A flowchart of operation

in standby mode is shown in figure 12.
