Direct Transition from Subactive Mode to Active Mode:
Available by controlling the direct transfer on
flag (DTON: $020, bit 3) and the low speed on flag (LSON: $020, bit 0). The procedures are described
below:
Set LSON to 0 and DTON to 1 in subactive mode.
Execute the STOP or SBY instruction.
The MCU automatically enters active mode from subactive mode after waiting for the MCU internal
processing time and oscillation stabilization time (figure 19).
Notes: 1. The DTON flag can be set only in subactive mode. It is always reset in active mode.
2. The transition time (T
