RESET CIRCUIT
Setting RSTB pin to “L” (hardware reset) or instruction RESET (software reset) can initialize internal function. Please note the
hardware reset is not same as the software reset. Generally, VDD1 is not stable at the time that the system power is just
turned ON. The hardware reset is required to initialize internal registers after VDD1 is stable. Initialization by RSTB pin is
essential before operating. The default values of registers are listed below:
