25.3.3
IFR2 is an interrupt flag register for SURSS, SURSF, CFDN, SOF, SETC, and SETI. When each
flag is set to 1 and an interrupt is enabled in the corresponding bit of IER2, an interrupt occurs as
specified by the corresponding bit in ISR2. Clearing is performed by writing 0 to the bit to be
cleared. Writing 1 is not valid and nothing is changed.

R/W USB Disconnection Detection
[Setting condition]
When data to be transmitted to the host is written to
EP3, then data is normally transferred from the host to
the function, and an ACK handshake is returned.
[Clearing conditions]
•
•
The USBF_VBUS pin of this module is used for
detecting connection/disconnection.
[Setting condition]
When the function is connected to the USB bus or
disconnected from it.
[Clearing conditions]

Reserved
These bits are always read as 0. The write value
should always be 0.
Suspend/Resume Status
Status bit indicating the state of the bus
0: Normal state
1: Suspend state
When reset
When 0 is written to by CPU
When reset
When 0 is written to by CPU.
