Endpoint Enable
Set this bit to enable the endpoint according to the device configuration. Endpoint 0 will
always be enabled after a hardware or USB bus reset and participate in the device
configuration.
Clear this bit to disable the endpoint according to the device configuration.
Reserved
The value read from this bit is always 0. Do not set this bit.
Reserved
The value read from this bit is always 0. Do not set this bit.
Reserved
The value read from this bit is always 0. Do not set this bit.
Data Toggle (Read-only)
This bit is set by hardware when a valid DATA0 packet is received and accepted.
This bit is cleared by hardware when a valid DATA1 packet is received and accepted.
Endpoint Direction
Set this bit to configure IN direction for Bulk, Interrupt and Isochronous endpoints.
Clear this bit to configure OUT direction for Bulk, Interrupt and Isochronous endpoints.
This bit has no effect for Control endpoints.
Endpoint Type
Set this field according to the endpoint configuration (Endpoint 0 will always be
configured as control):
00Control endpoint
01Isochronous endpoint
10Bulk endpoint
11Interrupt endpoint
