12.1.2 CCB interface
• The CCB interface is a SANYO’s original serial bus format based on LSB-first communication, but three-state is
• Data input/output is performed following CCB address input. The same CCB address cannot be used for both read and

DI1, command addresses of DI4 to DI7, and data of DI8 to DI15. DI2 and DI3 are reserved for the system. So, DI2
and DI3 input must be doing "0".

Pc data output
Input is performed in the following sequence: CCB addresses of A0 to A3 and B0 to B3, chip addresses of DI0 and
For the chip addresses, DI0 corresponds to CAL (low-order), and DI1 to CAU (high-order). For details, see section 9.2.
Read data is output from DO. DO is in the high impedance state when CE is "L", and begins outputting from the rising
If DO outputs are shared using multiple LC89058W-E units, it is possible to set the DO outputs of the LC89058W-E
The CCB interface uses CL of a normal L clock, and it is also possible to use CL of a normal H clock. However, input
CL is lowered before CE is raised when data reads.
