Regulator resistor select register: (R2, R1, R0) = (0, 0, 0)
Reference voltage control register (EV5, EV4, EV3, EV2, EV1, EV0) = (1, 0, 0, 0, 0, 0)
Other instruction registers : Not Changed
While RESETB is "L" or reset instruction is executed, no instruction except read status can be accepted. Reset
status appears at DB4. After DB4 becomes "L", any instruction can be accepted. RESETB must be connected to
the reset pin of the MPU, and initialize the MPU and this LSI at the same time. The initialization by RESETB is
essential before used.
