7707A–AVR–01/07
• RSTDT - Reset Data Toggle Bit
Set to automatically clear the data toggle sequence:
For OUT endpoint: the next received packet will have the data toggle 0.
For IN endpoint: the next packet to be sent will have the data toggle 0.
Cleared by hardware instantaneously. The firmware does not have to wait that the bit is cleared.
Clearing by software has no effect.
• 2 - Reserved
The value read from these bits is always 0. Do not set these bits.
• 1 - Reserved
The value read from these bits is always 0. Do not set these bits.
• 0 - EPEN - Endpoint Enable Bit
Set to enable the endpoint according to the device configuration. Endpoint 0 shall always be
enabled after a hardware or USB reset and participate in the device configuration.
Clear this bit to disable the endpoint. See Section , page 193 for more details.
• 7-6 - EPTYPE1:0 - Endpoint Type Bits
Set this bit according to the endpoint configuration:
00b: Control10b: Bulk
01b: Isochronous11b: Interrupt
• 5-1 - Reserved
The value read from these bits is always 0. Do not set these bits.
• 0 - EPDIR - Endpoint Direction Bit
Set to configure an IN direction for bulk, interrupt or isochronous endpoints.
Clear to configure an OUT direction for bulk, interrupt, isochronous or control endpoints.
• 7 - Reserved
The value read from these bits is always 0. Do not set these bits.
• 6-4 - EPSIZE2:0 - Endpoint Size Bits
Set this bit according to the endpoint size:
000b: 8 bytes
