Product data sheet
The RAM is structured in blocks of PTDs and payloads so that while the USB is executing
on an active transfer-based PTD, the processor can simultaneously fill up another block
area in the RAM. A PTD and its payload can then be updated on-the-fly without stopping
or delaying any other USB transaction or corrupting the RAM data.
Some of the design features are:

The address range of the internal RAM buffer is from 0400h to FFFFh.
The internal memory contains isochronous, interrupt and asynchronous PTDs, and
respective defined payloads.
All accesses to the internal memory are double-word aligned.
Internal memory address range calculation:
Memory address = (CPU address
