Even if the PID bits have been modified to NAK 
after this module has issued S-SPLIT of the split 
transaction for the selected pipe (while CSSTS 
indicates 1), this module continues the transaction 
until C-SPLIT completes. On completion of C-
SPLIT, this module sets PID to NAK. 

(2) When the function controller function is selected

This module modifies the setting of these bits as 
follows. 

  This module modifies PID to NAK on receiving 

the setup packet. Here, this module sets VALID 

to 1. PID cannot be modified until VALID is set 

to 0. 

  This module sets PID to STALL (11) on 

receiving the data of the size exceeding the 

maximum packet size when PID has been set to 

BUF. 

  This module sets PID to STALL (1x) on 

detecting the control transfer sequence error. 

  This module sets PID to NAK on detecting the 

USB bus reset. 

This module does not reference to the setting of the 
PID bits while the SET_ADDRESS request is 
processed (auto processing). 

Notes:  1.  This bit is always read as 0. Only 1 can be written. 

 

2.  Only 1 can be written.
