This bit indicates whether the relevant pipe is used or 
not for the transaction. 

0: The relevant pipe is not used for the transaction. 

1: The relevant pipe is used for the transaction. 

This module modifies this bit from 0 to 1 upon start of 
the USB transaction for the pertinent pipe, and clears 
it from 1 to 0 when one transaction completes 
successfully. 

Reading this bit after PID has been set to NAK 
allows checking that modification of the pipe settings 
is possible. 

For details, refer to section 26.4.3 (1), Pipe Control 
Register Switching Procedures.
