Chapter 22: LPC24XX I
2
C interfaces I
2
C0/1/2
If the AA bit is reset during a transfer, the I
2
C block will return a not acknowledge (logic 1)
to SDA after the next received data byte. While AA is reset, the I
2
C block does not
respond to its own slave address or a general call address. However, the I
2
C bus is still
monitored and address recognition may be resumed at any time by setting AA. This
means that the AA bit may be used to temporarily isolate the I
2
C block from the I
2
C bus.
