AT90USB64/128
• 1 - P1RST - Pipe 1 Reset
Set this bit to 1 and reset this bit to 0 to reset the Pipe 1.
• 0 - P0RST - Pipe 0 Reset
Set this bit to 1 and reset this bit to 0 to reset the Pipe 0.
• 7 - Reserved
The value read from this bit is always 0. Do not set this bit.
• 6 - PFREEZE - Pipe Freeze
Set this bit to Freeze the Pipe requests generation.
Clear this bit to enable the Pipe request generation.
This bit is set by hardware when:
- the pipe is not configured
- a STALL handshake has been received on this Pipe
- An error occurs on the Pipe (UPINTX.PERRI = 1)
- (INRQ+1) In requests have been processed
This bit is set at 1 by hardware after a Pipe reset or a Pipe enable.
• 5 - INMODE - IN Request mode
Set this bit to allow the USB controller to perform infinite IN requests when the Pipe is not frozen.
Clear this bit to perform a pre-defined number of IN requests. This number is stored in the UIN-
RQX register.
• 4 - Reserved
The value read from this bit is always 0. Do not set this bit.
• 3 - RSTDT - Reset Data Toggle
Set this bit to reset the Data Toggle to its initial value for the current Pipe.
Cleared by hardware when proceed. 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 - PEN - Pipe Enable
Set to enable the Pipe.
