RESET CIRCUIT

Setting RESETB to “L” or Reset instruction can initialize internal function.

When RESETB becomes “L”, following procedure is occurred.

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: 1/7 (1/65 duty), 1/6 (1/49 duty), 1/5 (1/33 duty)

Read-modify-write: OFF

SHL select: OFF (normal)

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) = (0, 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 is occurred.

Read-modify-write: OFF

Static indicator mode: OFF

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.
