USB device endpoint
registers
206
• 7-3 - Reserved
The value read from these bits is always 0. Do not set these bits.
• 2-0 - EPNUM2:0 Endpoint Number Bits
Set to select the number of the endpoint which shall be accessed by the CPU. See Section ,
page 193 for more details.
Values greater than 100b are forbidden.
• 7-5 - Reserved
The value read from these bits is always 0. Do not set these bits.
• 4-0 - EPRST4:0 - Endpoint FIFO Reset Bits
Set to reset the selected endpoint FIFO prior to any other operation, upon hardware reset or
when an USB bus reset has been received. See Section , page 192 for more information
Then, cleared by software to complete the reset operation and start using the FIFO.
• 7-6 - Reserved
The value read from these bits is always 0. Do not set these bits.
• 5 - STALLRQ - STALL Request Handshake Bit
Set to request a STALL answer to the host for the next handshake.
Cleared by hardware when a new SETUP is received. Clearing by software has no effect.
See Section , page 195 for more details.
• 4 - STALLRQC - STALL Request Clear Handshake Bit
Set to disable the STALL handshake mechanism.
Cleared by hardware immediately after the set. Clearing by software has no effect.
See Section , page 195 for more details.
