Table 26.28  Error Detection when a Data Packet is Received 
Detection 
Priority Order 
Error 
Generated Interrupt and Status 
1 
PID errors 
No interrupts are generated (ignored as 
a corrupted packet) 
2 
CRC error and bit stuffing errors 
An NRDY interrupt is generated to set 
the CRCE bit in both cases when the 
host controller function is selected and 
the function controller function is 
selected. 
3 
Maximum packet size exceeded error 
A BEMP interrupt is generated to set 
the PID bits to STALL in both cases 
when the host controller function is 
selected and the function controller 
function is selected. 
 
(2)  DATA-PID 
This module does not support High Bandwidth transfers. When the function controller function is 
selected, this module operates as follows in response to the received PID. 
(a)  IN direction 
  DATA0: Sent as data packet PID 
  DATA1: Not sent 
  DATA2: Not sent 
  mDATA: Not sent 
 
(b)  OUT direction (when using full-speed operation) 
  DATA0: Received normally as data packet PID 
  DATA1: Received normally as data packet PID 
  DATA2: Packets are ignored 
  mDATA: Packets are ignored 
 
(c)  OUT direction (when using high-speed operation) 
  DATA0: Received normally as data packet PID 
  DATA1: Received normally as data packet PID 
  DATA2: Received normally as data packet PID 
  mDATA: Received normally as data packet PID
