Two-Wire Serial Register Interface

Sequential READ, Start from Random Location

This sequence (Figure 10) starts in the same way as the single READ from random loca-

tion (Figure 8). Instead of generating a no-acknowledge bit after the first byte of data has

been transferred, the master generates an acknowledge bit and continues to perform

byte READs until “L” bytes have been read.

Sequential READ, Start from Current Location

This sequence (Figure 11) starts in the same way as the single READ from current loca-

tion (Figure 9 on page 19). Instead of generating a no-acknowledge bit after the first byte

of data has been transferred, the master generates an acknowledge bit and continues to

perform byte READs until “L” bytes have been read.

Single WRITE to Random Location

This sequence (Figure 12) begins with the master generating a start condition. The slave

address/data direction byte signals a WRITE and is followed by the HIGH then LOW

bytes of the register address that is to be written. The master follows this with the byte of

write data. The WRITE is terminated by the master generating a stop condition.
