Description
Indicates that the USB function core detects a bus reset
by an up-stream.
If the BRSTE bit in USBIER0 is set to 1, an USBID
interrupt is requested to the slave CPU.
[Clearing condition]
[Setting condition]
Indicates that the USB function core detects an SOF
(Start of Frame) by an up-stream.
If the SOFE bit in USBIER0 is set to 1, an USBID
interrupt is requested to the slave CPU.
[Clearing condition]
[Setting condition]
Indicates that the USB function core detects a bus state
transition from suspend state to normal state.
If the SPNDE bit in USBIER0 is set to 1, an USBID
interrupt is requested to the slave CPU.
[Clearing condition]
[Setting condition]
0 is written to after BRSTF = 1 has been read.

stream.
0 is written to after SOFF = 1 has been read.
The USB function core detects an SOF (Start of
Frame).
0 is written to after SPNDOF = 1 has been read.
The USB function core detects a bus state transition
from suspend state to normal state.
