Assert Acknowledge
. A logic 1 indicates that an ACK (low
level on SDA during acknowledge pulse on SCL) is returned
for one of the following conditions:
own slave address received
General Call address received, if bit GC = 1 (I2C0CON)
data byte received when in master receive mode
data byte received when addressed in slave receiver
mode.
