This register determines the maximum packet size for all endpoints, except set-up token
buffer, control IN and control OUT. 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 microframe (for high-speed isochronous and interrupt endpoints only).
