Register Name:
Access Type:
Reset Value:
• INRQ: IN Request Number before Freeze
Enter the number of IN transactions before the USB controller freezes the pipe. The USB controller will perform (INRQ+1)
IN requests before to freeze the Pipe. This counter is automatically decreased by 1 each time a IN request has been suc-
cessfully performed.
This register has no effect when the INMODE bit is set (infinite IN requests generation till the pipe is not frozen).
• 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 the INRQ field.
