This register determines the maximum packet size for all endpoints, except control 0. The
register contains 2 bytes, and the bit allocation is given in
Each time the register is written, the Buffer Length register of the corresponding endpoint
is re-initialized to the FFOSZ field value. Bits NTRANS control the number of transactions
allowed in a single micro frame (for high-speed isochronous and interrupt endpoints only).
