Register 17: USB Transmit Dynamic FIFO Sizing (USBTXFIFOSZ), offset 0x062
Register 18: USB Receive Dynamic FIFO Sizing (USBRXFIFOSZ), offset 0x063
These 8-bit registers allow the selected TX/RX endpoint FIFOs to be dynamically sized. USBEPIDX
is used to configure each transmit endpoint's FIFO size.

Description
Software should not rely on the value of a reserved bit. To provide
compatibility with future products, the value of a reserved bit should be
preserved across a read-modify-write operation.
Double Packet Buffer Support
Defines whether double-packet buffering is supported. When 1,
double-packet buffering is supported. When 0, only single-packet
buffering is supported.
Max Packet Size
Maximum packet size to be allowed for (before any splitting within the
FIFO of bulk/high-bandwidth packets prior to transmission.
If DPB = 0, the FIFO also is this size; if DPB = 1, the FIFO is twice this
size.
