29 / 38 page LC75808W No.6370-29/38 2. LC75808W internal block states during the system reset • CLOCK GENERATOR Reset is applied and the base clock is stopped. However, the OSC pin state (normal or sleep mode) is determined after the SP control data bit is transferred. • COMMON DRIVER, SEGMENT DRIVER & LATCH Reset is applied and the display is turned off. However, display data can be input to the latch circuit in this state. • CONTRAST ADJUSTER Reset is applied and operation of the display contrast adjustment circuit is disabled. After that, once CT0 to CT3 and CTC in the control data have been transferred to the IC it will then be possible to set the display contrast. • KEY SCAN, KEY BUFFER Reset is applied, these circuits are forcibly initialized internally, and key scan operation is disabled. Also, the key data is all set to 0. After that, once KC1 to KC6 in the control data have been transferred to the IC it will then be possible to perform key scan operations. • GENERAL PORT Reset is applied and the states of the general-purpose output ports are held fixed at the low level (VSS). • CCB INTERFACE, SHIFT REGISTER, CONTROL REGISTER Since serial data transfer is possible, these circuits are not reset. 3. Output pin states during the system reset Output pin State during reset S1 to S60 COM1 to COM10 KS1 to KS6 P1 to P4 DO L(VLCD4) L(VLCD4) L(VSS) L(VSS) H *5 Note: *5. Since this output pin is an open-drain output, a pull-up resistor of between 1k Ω and 10 kΩ is required. This pin is held at the high level even if a key data read operation is performed before the KC1 to KC6 control data has been transferred to the IC.
