RESET MODE
The module is reset automatically at power-up by internal R-C circuit. However, an
external reset mode can also be selected when using one of the parallel interface modes
(this option is not available when using the synchronous serial interface mode) which
allows the module to be reset by setting the Reset (RST/) input low.
