C-bus protocol
Before any data is transmitted on the I
2
C-bus, the device which should respond is addressed first. The addressing is
always carried out with the first byte transmitted after the start procedure. The I
2
C-bus configuration for the different
PCA8581 WRITE and READ cycles is shown in Figs 7, 9 and 10.
After the word address, one-to-eight data bytes can be sent. The address is automatically incremented, but the four
highest address bits (row) are internally latched. Therefore all bytes are written in the same row.
An example of writing eight bytes with word address X 0 0 0 0 0 0 0 and six bytes with word address X 0 0 1 0 1 0 1 is
shown in Fig.8.
