EOF Error Detection Interrupt Status 
Indicates the status of the EOFERR interrupt when 
the host controller function is selected. 
0: EOFERR interrupt not generated 
1: EOFERR interrupt generated 
This module detects the EOFERR interrupt on 
detecting that communication is not completed at the 
EOF2 timing prescribed by USB Specification 2.0, 
and sets this bit to 1. Here, if the corresponding 
interrupt enable bit has been set to 1, this module 
generates the EOFERR interrupt.  
After detecting the EOFERR interrupt, this module 
controls hardware as described below (irrespective 
of the set value of the corresponding interrupt enable 
bit). Terminate all the pipes in which communications 
are currently carried for the USB port and perform re-
enumeration of the USB port. 
(1) Modifies the UACT bit to 0. 
(2) Causes a transition to the idle state. 
When the function controller function is selected, the 
read value is invalid.
