7.2 Chip Address Settings (EMPHA/UO, AUDIO/VO)
The LC89057W-VF4-E comes with a function to set a unique chip address to allow the use of several LC89057W-
VF4-E on the same microcontroller bus.
Connect a 10k
pull-down or pull-up resistor to EMPHA/UO and AUDIO/VO as the chip address settings. This
allows up to set 4 chip addresses.
Chip addresses in the microcontroller interface are set with CAL and CAU provided as the first two bits on the LSB
side. CAL corresponds to the lower and CAU to the higher chip address.
Command writing is enabled by making the chip address settings using EMPHA/UO and AUDIO/VO the same as
the chip addresses sent from the microcontroller.
The chip address setting must be performed even when using only one LC89057W-VF4-E in the system. If the chip
address setting is not performed, the chip address is undefined and control from the microcontroller cannot be
performed. When the microcontroller is not used, the state of the 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 EMPHA/UO and AUDIO/VO.
