Field Documentation

Supplies the alignment requirement for any buffer used in a data transfer. IoAlign values of 0 and 1 mean that the buffer can be placed anywhere in memory. Otherwise, IoAlign must be a power of 2, and the requirement is that the start address of a buffer must be evenly divisible by IoAlign with no remainder.
