Hi All,
I would like to ask some questions on flash.
The manual of the NOR flash used on EVM6437 lists many XXXs as command addresses. In the real code for read, write and erase operation, I found that the XXXs are replaced by 0xAAA.
In general, X means “don’t care” in logic truth table, but it nevertheless must have a particular embodiment. So is 0xAAA the arbitrarily chosen embodiment for XXX, and anything else would also work in place of 0xAAA?
Thanks,
Zheng
