In the I
the serial control port clock, SCL (see Figure 7 for the clock to data relationship). There is no CS
pin. Pin AD0 enables the user to alter the chip address (001000[AD0][R/W]) and should be tied to
VA or GND as required, before powering up the device. If the device ever detects a high to low
transition on the AD0/CS pin after power-up, SPI mode will be selected.

To write to the device, follow the procedure below while adhering to the control port
Switching Specifications in section 7.
1) Initiate a START condition to the I
must be 001000. The seventh bit must match the setting of the AD0 pin, and the eighth must
be 0. The eighth bit of the address byte is the R/W bit.
2) Wait for an acknowledge (ACK) from the part, then write to the memory address pointer,
MAP. This byte points to the register to be written.
3) Wait for an acknowledge (ACK) from the part, then write the desired data to the register
pointed to by the MAP.
4) If the INCR bit (see section 3.9.2) is set to 1, repeat the previous step until all the desired
registers are written, then initiate a STOP condition to the bus.
5) If the INCR bit is set to 0 and further I
essary to initiate a repeated START condition and follow the procedure detailed from step
1. If no further writes to other registers are desired, initiate a STOP condition to the bus.
