36.3.38 Endpoint Information Register (EPIR)

EPIR is a register to set the configuration information for each endpoint. 5 bytes of the

information are required for one endpoint and the formats are listed in tables 36.4 and 36.5. Write

the data in order from endpoint 0. Do not write more than 5 (bytes) × 10 (endpoints) = 50 bytes.

Write this information once at power-on reset. Do not write it again afterwards.

Write data of one endpoint is described below. EPIR writes data in the same address in order.

Therefore though there is only one EPIR register, write data for registration number N (N is from

0 to 9) is listed as EPIRN0 to EPIRN4 (EPIR [registration number] [write order]) for the purpose

of explaining. Write data in order from EPIR00.

Initial value:

Initial value R/W Description

These bits are always read as undefined value.

Write value should always be 0.
