This field is incremented each time an error occurs (CRC16, TIMEOUT, PID, DATAPID or DATATGL).
This field is cleared when receiving a good usb packet without any error.
When this field reaches 3 (i.e., 3 consecutive errors), this pipe is automatically frozen (UPCONn.PFREEZE is set).
Writing 0b00 to this field will clear the counter.
This bit is set when a CRC16 error has been detected.
Writing a zero to this bit will clear the bit.
Writing a one to this bit has no effect.
This bit is set when a Time-Out error has been detected.
Writing a zero to this bit will clear the bit.
Writing a one to this bit has no effect.
This bit is set when a PID error has been detected.
Writing a zero to this bit will clear the bit.
Writing a one to this bit has no effect.
This bit is set when a Data PID error has been detected.
Writing a zero to this bit will clear the bit.
Writing a one to this bit has no effect.
This bit is set when a Data Toggle error has been detected.
Writing a zero to this bit will clear the bit.
Writing a one to this bit has no effect.
