Preliminary
RESET CIRCUIT
Internal function can be initialized by setting RESETB to low or Reset instruction.
When RESETB becomes low, following procedure occurs.
— Display ON/OFF:OFF
— Entire display ON/OFF: OFF (Normal)
— ADC select: OFF (Normal)
— Reverse display ON/OFF: OFF (Normal)
— Power control register (VC, VR, VF) = (0, 0, 0)
— LCD bias ratio: 1/8 (1/55 Duty), 1/6 (1/34 Duty)
— Modify-read: OFF
— SHL select: 0
— Static indicator mode: OFF
Static indicator register: (S1, S0) = (0, 0)
— Display start line: 0 (First)
— Column address: 0
— Page address: 0
— Regulator resistor select register: (R2, R1, R0) = (1, 0, 0)
— Reference voltage set: OFF,
Reference voltage control register: (SV5, SV4, SV3, SV2, SV1, SV0) = (1, 0, 0, 0, 0, 0)
When RESET instruction is issued, following procedure occurs.
— Modify-read: OFF
— Static indicator mode: OFF
Static indicator register: (S1, S0) = (0, 0)
— SHL select: 0
— Display start line: 0 (First)
— Column address: 0
— Page address: 0
— Regulator resistor select register: (R2, R1, R0) = (1, 0, 0)
— Reference voltage set: OFF
Reference voltage control register (SV5, SV4, SV3, SV2, SV1, SV0) = (1, 0, 0, 0, 0, 0)
While RESETB is low or reset instruction is executed, no instruction except read status can be accepted. Reset
status appears at DB4. After DB4 becomes low, any instruction can be accepted.
RESETB pin must be connected to the reset pin of MPU, and initialize the MPU and this LSI at the same time. The
initialization by RESETB pin is essential before used.
