20.3.25 Endpoint Information Register (EPIR)
This register sets the information for each endpoint. Each endpoint needs five bytes to store the
information. Writing data should be done in sequence starting at logical endpoint 0. Do not write
data of more than 50 bytes (five bytes multiplied by ten endpoints) to this register. The
information should be written to this register only once at reset and no data should be written after
that. Description of writing data for one endpoint is shown below.
Although this register consists of one register to which data is written sequentially for one address,
the write data for the endpoint 0 is described as EPIR00 to EPIR05 (EPIR endpoint number in
write order) to make the explanation understood easier. Write should start at EPIR00.
