Bit 8 – INMODE IN Request Mode
| Value | Description |
|---|---|
| 0 | Performs a pre-defined number of IN requests. This number is the INRQ field. |
| 1 | Enables the USBHS to perform infinite IN requests when the pipe is not frozen. |
Bits 7:0 – INRQ[7:0] IN Request Number before Freeze
This field contains the number of IN transactions before the USBHS freezes the pipe. The USBHS performs (INRQ+1) IN requests before freezing the pipe. This counter is automatically decreased by 1 each time an IN request has been successfully performed.
This register has no effect when INMODE = 1.
