Before setting PID to BUF for the selected pipe 
(before starting USB communication using the 
selected pipe), be sure to set these bits to the value 
other than 00. 

Modify these bits while the PID bits for the selected 
pipe are set to NAK. Before modifying these bits after 
modifying the PID bits for the selected pipe from BUF 
to NAK, check that CSSTS and PBUSY are 0. 
However, if the PID bits have been modified to NAK 
by this module, checking PBUSY is not necessary.
