8.2 Chip Address Settings (EMPHA/UO,
______
AUDIO/VO)
The LC89057W-VF4 comes with a function to set a unique chip address to allow the use of several LC89057W-VF4
on the same microcontroller bus.
In chip address setting, a 10k pull-down or pull-up resistor is connected with EMPHA/UO and
______
AUDIO/VO. By this
setting, 4 kinds of chip addresses can be set at a maximum.
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 chip address and CAU to the higher chip address.
Command writing becomes possible by making the chip address settings with EMPHA/UO and
______
AUDIO/VO identical
to the chip addresses sent from the microcontroller.
The chip address setting is required even when only one LC89057W-VF4 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 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.
