9.3.5 Endpoint MaxPacketSize register (address: 04H)
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 registers of all endpoints are
re-initialized to the FFOSZ field value. The NTRANS bits control the number of
transactions allowed in a single micro-frame (for high-speed Isochronous and
interrupt endpoints only).
