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.
