Reset is accomplished by applying an external reset pulse
(active LOW) at pad RES. When reset occurs within the
specified time, all internal registers are reset, however the
RAM is still undefined. The state after reset is described in
Section 13.3. Pad RES must be 0.3V

A reset can also be achieved by sending a reset
command. This command can be used during normal
operation but not to initialize the chip after power-on.
