7.4.2 nENBL and RESET Operation

The nENBL pin enables or disables the output drivers. nENBL must be low to enable the outputs. Note that nENBL has an internal pulldown.

The RESET pin, when driven active high, resets internal logic. All inputs are ignored while RESET is active. Note that RESET has an internal pulldown. An internal power-up reset is also provided, so it is not required to drive RESET at power up.
