9.2 Chip Address Settings (MOUT,
• The LC89058W-E comes with a function to set a unique chip address to allow the use of several LC89058W-E on the
• In chip address setting, connect a 10kΩ pull-down or pull-up resistor to MOUT and
• Chip addresses in the microcontroller interface are set with CAL and CAU provided as the first two bits on the LSB
• Command writing is enabled by making the chip address settings with MOUT and
• The chip address setting is required even when only one LC89058W-E is used in the system. If the chip address is not

set, the chip address is undefined and the microcontroller cannot control the system. When the microcontroller is not
used, a chip address-setting pin is input open while XMODE is "L". Be sure to connect either a pull-down resistor or a
pull-up resistor to MOUT and
