The USB con- troller 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 set (infinite IN requests generation till the pipe is not frozen). • 7-6 - Reserved The value read from these bits is always 0. Do not set these bits. • 5 - COUNTER1:0 - Error counter This counter is increased by the USB controller each time an error occurs on the Pipe. When this value reaches 3, the Pipe is automatically frozen. Clear these bits by software. • 4 - CRC16 - CRC16 Error Set by hardware when a CRC16 error has been detected. Shall be cleared by software. Setting by software has no effect. • 3 - TIMEOUT - Time-out Error Set by hardware when a time-out error has been detected. Shall be cleared by software. Setting by software has no effect. • 2 - PID - PID Error Set by hardware when a PID error has been detected. Shall be cleared by software. Setting by software has no effect. • 1 - DATAPID - Data PID Error Set by hardware when a data PID error has been detected. Shall be cleared by software. Setting by software has no effect. • 0 - DATATGL - Bad Data Toggle Set by hardware when a data toggle error has been detected. Shall be cleared by software. Setting by software has no effect.
