For a single packet read and write operations must pick either 32-bit, 16-bit or 8-bit read or write operations. Mixing and matching can cause corruption of data. This becomes a bigger issue when using TinyUSB fifo that has to deal with wrapping since read/write operations may be split between multiple transfers of different sizes. Therefore, create a function that will determine which operation can be used for transfer the entire buffer of data. Then read and write operations can use a parameter to determine what should be used. Signed-off-by: Franklin Cooper Jr <fcooper@ti.com>
