WRITE cycle
Table 13 shows the I
2
C-bus configuration for a WRITE cycle. The WRITE cycle is used to write the data to the internal registers. The device and register
addresses are one byte each, the setting data is always a pair of two bytes.
The format of the WRITE cycle is as follows:
1.
The microcontroller starts with a start condition (S).
2.
The first byte (8 bits) contains the device address ‘00110A10’ and a logic 0 (WRITE) for the bit R/W.
3.
This is followed by an acknowledge (A) by the UDA1380.
4.
After this the microcontroller writes the register address (ADDR) (8 bits) where the writing of the register content of the UDA1380 must start.
5.
The UDA1380 acknowledges this register address (A).
6.
The UDA1380 sends the two-bytes data with the Most Significant (MS) byte first, and then the Least Significant (LS) byte, each time acknowledged
by the microcontroller.
7.
The UDA1380 stops this cycle by generating an acknowledge (A).
8.
Finally, the UDA1380 frees the I
2
C-bus and the microcontroller can generate a stop condition (P).
