C Address Bit Map
Figure 4 illustrates the address bit map format. The
7-bit address is sent with the Most Significant Bit
(MSB) first and is valid when SCL is high. This is fol-
lowed by the R/W bit in the Least Significant Bit
(LSB) location. The R/W bit determines the direction
of the transfer ('1' for read, '0' for write). The
AAT1142 is a write-only device and this bit must be
set low when communicating with the AAT1142. The
Acknowledge bit (ACK) is set to low by the AAT1142
slave to acknowledge receipt of the address.
