19.7.2.8 Endpoint Enable/Reset Register

Access Type: Read/Write

Offset: 0x001C

Reset Value: 0x00000000

• EPENn: Endpoint n Enable

Note: 1. EPENn bits are within the range from EPEN0 to EPEN6.

Writing a zero to this bit will disable the endpoint n (USB requests will be ignored), and resets the endpoints registers (UECFGn,

UESTAn, UECONn), but not the endpoint configuration (EPBK, EPSIZE, EPDIR, EPTYPE).

Writing a one to this bit will enable the endpoint n.

0: The endpoint n is disabled.

1: The endpoint n is enabled.
