C-BUS SPECIFICATION
The slave addresses of the IC are given in Table 3. The circuit operates at clock frequencies of up to 400 kHz.
Table 3
Slave addresses (9A or 9E)
Bit A1 is controlled via the ADR pin, when the pin is connected to ground A1 = 0 and when connected to the positive
supply line A1 = 1. When this pin is left open it is connected to ground via an internal resistor.

Input control registers
Table 4
Input control registers; valid subaddresses: 00 to 0F; auto-increment mode available for subaddresses
Note
1.
The value of this bit cannot be changed.
