STOP instruction
RESET input
STOP mode
HALT mode
(oscillator stabilization time)
Clock oscillation starts
Released
Ordinary reset operation
(execution starts from
address 0)
Caution The STOP mode is not released by setting the test request flags.
3.4 RELEASING HALT MODE BY USING TEST REQUEST FLAGS
The HALT is released when either or both of the test request flags (INTT RQF and INT0 RQF) are set, and program
execution is resumed, starting from the instruction next to the HALT instruction.
The contents of the registers and data memory, which have been retained during the HALT mode, are not
affected by the release of the HALT mode.
3.5 RELEASING HALT MODE BY USING RESET INPUT
When the RESET signal is input, the HALT mode is unconditionally released, as illustrated in Fig. 3-2.
Fig. 3-2 HALT Mode Release Timing by RESET Input
Fig. 3-1 STOP Mode Release Timing
RESET
HALT mode
Released
Ordinary reset operation
(execution starts from
address 0)
While the RESET signal is active (high level), the HALT mode continues. When the RESET signal goes low, the
HALT mode is released. Ordinary resetting operation is then accomplished. Then, the program is executed starting
from address 0.
The contents of the data memory, retained during the HALT mode, are not affected by the RESET signal.
However, the contents of the registers are affected and become undefined.
