R/W*¹ 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 software has set the
corresponding interrupt enable bit 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). Software should terminate all the pipes in which
communications are currently carried for the USB
port and perform re-enumeration of the USB port.
• Modifies the UACT bit for the port in which an
EOFERR interrupt has been detected to 0.
• Puts the port in which an EOFERR interrupt has
been generated into the idle state.
When the function controller function is selected, the
read value is invalid.
