Table 119. I
If a repeated START condition is transmitted, the status code is
08h
After each data byte is transmitted, the IFLG is set to 1 and one of the status
codes listed in Table 120 is loaded into the I2C_SR register.

38h
68h
B0h

D8h
Notes:
1. W is defined as the Write bit; i.e., the lsb is cleared to 0.
2. AAK is an I 2 C control bit that identifies which ACK signal to transmit.
3. R is defined as the Read bit; i.e., the lsb is set to 1.
