13.13 POST RAM — Address 00h–1Fh
The address pointer for the POST RAM auto-increments when written to at Port x0h or x4h. Once the address pointer reaches
1Fh, a FIFO overflow interrupt will be generated and the FIFO will stop incrementing. Normal reads via Port x5h and x6h
auto-increment a separate pointer, and will not cause a FIFO overflow interrupt.
13.14 Value RAM — Address 20h–3Fh or 60h–7Fh (auto-increment)
