5. STANDBY FUNCTION
5.1 Outline of Standby Function
To save current consumption, two types of standby modes, i.e., HALT mode and STOP mode, are made available.
In STOP mode, the system clock stops oscillation. At this time, the X
IN
and X
OUT
pins are fixed at a low level.
In HALT mode, CPU operation halts, while the system clock continues oscillation. When in HALT mode, the
timer (including REM output and LED output) operates.
In either STOP mode or HALT mode, the statuses of the data memory, accumulator, and port register, etc.
immediately before the standby mode is set are retained. Therefore, make sure to set the port status for the system
so that the current consumption of the whole system is suppressed before the standby mode is set.

Cautions
1. Write the NOP instruction as the first instruction after STOP mode is canceled.
2. When standby mode is canceled, the status flag (F) is set (to 1).
3. If, at the point the standby mode has been set, its cancelation condition is met, then the
system is not placed in the standby mode. However, the status flag (F) is set (1).
