11.1.2 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 is employed instead of open-drain 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.

11.1.3 Data write procedure
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
8.2.
11.1.4 Data read procedure
Read data is output from DO. DO is in the high impedance state when CE is "L", and begins outputting from the
rising edge of CE after output setting is established at the CCB address. DO then returns to the high impedance state
at the falling edge of CE.
If DO outputs are shared using multiple LC89057W-VF4 units, it is possible to set the DO outputs of the LC89057W-
VF4 units of which data is not to be read to be always in the high impedance state with DOEN. With this setting, only
the targeted outputs can be read.
