C BUS FORMAT
The I

C-bus interface input format is shown below.
As mentioned above, the write operation can be executed from subaddress to subaddress
continuously. When the write operation is executed at subaddresses discontinuously, the
Acknowledge and Stop condition formats are input repeatedly after Data 0.
If one of the following matters occurs, the decoder will not return "A" (Acknowledge).
The slave address does not match.
A non-existent subaddress is specified.
The write attribute of a register does not match "X" (read/write control bit).
The input timing is shown below.
