Description
Indicates that the USB function core detects an idle state
for a specific period or more, and detects a bus state
transition from normal state to suspend state.
If the SPNDE bit in USBIER0 is set to 1, an USBID
interrupt is requested to the slave CPU.
[Clearing condition]
[Setting condition]
The meaning of this bit differs depending on the
SETICNT bit in USBMDCR.
When SETICNT = 0, Indicates that endpoint 0 of the
USB function core receives a SETUP token.
When SETICNT = 1, Indicates that endpoint 0 of the
USB function core receives a setup command that must
be decoded by the slave CPU.
If the SETUPE bit in USBIER0 is set to 1, an USBIA
interrupt is requested to the slave CPU.
[Clearing condition]
[Setting conditions]
0 is written to after SPNDIF = 1 has been read.
The USB function core detects s bus state transition
from normal state to suspend state.
0 is written to after SETUPF = 1 has been read.
Endpoint 0 of the USB function core receives a
SETUP token (when SETICNT = 0).
Endpoint 0 of the USB function core receives a setup
command to be decoded by the slave CPU (when
SETICNT = 1).
