7.27 Discharge circuit
The EM65567 has built-in the discharge circuit, which discharges electricity from capacitors for a stability of power
sources(V0~V4).
The discharge circuit is valid, while the DIS register is set to “1” or the RESB pin is set “L”. When the built-in power supply
is used, should be set DIS=”1” after the power source is turned off (DCON, AMPON)=(0, 0). And don’t turn on both the
built-in power source and the external power source (V0~V4, VOUT) while DIS=”1”.
7.28 Initialization
The EM65567 is initialized by setting RESB pin to “L”. Normally, RESB pin is initialized together with MPU by connecting
to the reset pin of MPU. When power ON, be sure to make RESB=”L”.
