competent retailers.
7.6 RESET
7.6.1 General presentation
This signal is used to force a reset procedure by providing low level during at least
500 µs.
This signal must be considered as an emergency reset only
. A reset procedure is
automatically driven by an internal hardware during the power-up sequence.
This signal may also be used to provide a reset to an external device. It then behaves
as an output. If no external reset is necessary, this input may be left open, if used
(emergency reset), it has to be driven either by an open collector or an open drain
output:
• RESET pin 14 = 0, for M1306B Reset,
• RESET pin 14 = 1, for normal mode.

Additional comments on RESET:
The RESET process is activated either by the external RESET signal or by an internal
signal (coming from a RESET generator). This automatic reset is activated at Power-
up.
The M1306B remains in RESET mode as long as the RESET signal is held low.
Caution:
This signal should be used only for "emergency" reset.
A software reset is always preferred to a hardware reset.
Note
: See "AT Commands Interface Guide" [7] for further information on software
reset.
