Section 18 Universal Serial Bus Interface (USB)
Description
R/(W) * Bus Reset Interrupt Status
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]
•
0 is written to after BRSTF = 1 has been read.
[Setting condition]
•
The USB function core detects a bus reset by an up-
stream.
R/(W) * SOF Interrupt Status
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]
•
0 is written to after SOFF = 1 has been read.
[Setting condition]
•
The USB function core detects an SOF (Start of
Frame).
R/(W) * Suspend OUT Interrupt Status
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]
•
0 is written to after SPNDOF = 1 has been read.
[Setting condition]
•
The USB function core detects a bus state transition
from suspend state to normal state.
