39.6.3.20 Host Pipe x IN Request Register
Name: UOTGHS_HSTPIPINRQx [x=0..9]
Address: 0x400AC650
Access: Read-write
• INMODE: IN Request Mode
Writing a one to this bit will allow the UOTGHS to perform infinite IN requests when the Pipe is not frozen.
Writing a zero to this bit will perform a pre-defined number of IN requests. This number is the INRQ field.
• INRQ: IN Request Number before Freeze
This field contains the number of IN transactions before the UOTGHS freezes the pipe. The UOTGHS 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 successfully performed.
This register has no effect when the INMODE bit is one (infinite IN requests generation till the pipe is not frozen).
