If an overflow occurs when incrementing the previous write address, the address wraps to 0, and the way is toggled.
The write data is identical to the previous write data.
For proper results, an auto-increment write must always be proceeded by a normal or auto-increment write.
The external agent issues an auto-increment write command by:
