Documentation

This is the layout of the 5588 register area. The 5588 registers are sensitive to correct size and alignment of read/write operations. Using this structure will ensures the correct alignment and sizing of register accesses.
NOTE:The align* members are only there for correct memory sizing and alignment. Reading/writing from/to the align* members is not recommended.
