Endpoint Configuration Example

Figure 15.26 shows an example of endpoint configuration. EPINFO data for the endpoint
configuration shown in figure 15.26 is shown in table 15.8. In this example, two endpoints are not
used. However, note that to load all EPINFO data from UEP1R00_0 to UEPIR22_4, dummy data
must be written to the unused endpoints. An example of dummy data is also shown in table 15.8.
Configuration 1
If endpoints are configured as shown in figure 15.26, some register names change as shown in
table 15.7. In addition, some register bit names also change as shown in table 15.8. In the example
shown in figure 15.26, register or bit names are modified for those determined based on the
Bluetooth standard as follows: EP1i→ EP3, EP2i→ EP2, EP2o→ EP1, EP4i→ EP5, EP4o→ EP6,
and EP5i→ EP4.
