The EM65571 has a built-in discharge circuit, which discharges electricity from capacitors
for stability of power sources (V0~V4).
The discharge circuit is valid, while the DIS register is set to “1”. When the built-in power
supply is used, it should be set DIS=”1” after the power source is turned off (DCON,
AMPON) = (0, 0). Both the built-in power source and the external power source (V0~V4,
VOUT) should not be turned off while DIS= ”1”.
Setting RESB pin to “L” initializes the EM65571. Normally, the RESB pin is initialized
together with the MPU by connecting to the reset pin of the MPU. When power is ON, be
sure to make RESB=”L”.
