Reset
The MT9M114 has 3 types of reset available:
• A hard reset is issued by toggling the RESET_BAR signal
• A soft reset is issued by writing commands through the two-wire serial interface
• An internal power-on reset
The output states during hard reset are shown in Table 5.

A soft reset sequence to the sensor has the same effect as the hard reset and can be acti-
vated by writing to a register through the two-wire serial interface. On-chip power-on-
reset circuitry can generate an internal reset signal in case an external reset is not
provided. The RESET_BAR and CONFIG signals have internal pull-up resistors and can
be left floating.
