10.1.2 CCB format
The various function settings as well as information writing and reading are performed with the microcontroller
interface.
The data format of the microcontroller interface conforms to Sanyo's original serial bus format (CCB), but three-
state instead of open-drain is employed for the data output format.
Data input/output is performed following CCB address input. For the data input/output timing, see the input/output
timing chart.

10.1.3 Data write method
Input is performed in the following sequence: CCB addresses of A0 to A3 and B0 to B3, chip addresses of DI0 and
DI1, command addresses of DI4 to DI7, and data of DI8 to DI15. DI2 and DI3 are reserved for the system. Input
"0".
For the chip addresses, DI0 corresponds to CAL (low-order), and DI1 to CAU (high-order). For details, see section
7.2.
10.1.4 Data read method
Read data is output from DO. DO is in the high impedance state when CE is "L", and begins output from the rising
edge of CE after output setting is satisfied at the CCB address. DO then returns to the high impedance state at the
falling edge of CE.
If DO outputs using multiple LC89057W-VF4-E units are shared, the DO outputs of the LC89057W-VF4-E units
for which data read is to be performed can be set to always be in the high impedance state with DOEN. With this
setting, it is possible to read only the desired outputs.
