IFR2, together with interrupt flag registers 0 and 1 (IFR0 and IFR1), indicates interrupt status
information required by the application. When an interrupt source is generated, the corresponding
bit is set to 1. And then this bit, in combination with interrupt enable register 2 (IER2), generates
an interrupt request to the CPU. To clear, write 0 to the bit to be cleared and 1 to the other bits.

Description
USB Disconnection Detection
When the function is connected to the USB bus or
disconnected from it, this bit is set to 1. The VBUS pin
of this module is used for detecting connection or
disconnection.
(When the CPU is used to clear this flag by writing 0
while the corresponding interrupt is enabled, be sure to
read the flag after writing 0 to it.)
Description
Reserved
These bits are always read as 0. The write value
should always be 0.
Suspend/Resume Status
This is a status bit that describes bus state.
0: Normal state
1: Suspended state
This bit is a status bit and generates no interrupt
request.
