If there has been a change in the VBUS pin, the VBUS interrupt is generated. The level of the
VBUS pin can be checked with the VBSTS bit in INTSTS0. Whether the host controller is
connected or disconnected can be confirmed using the VBUS interrupt. However, if the system is
activated with the host controller connected, the first VBUS interrupt is not generated because
there is no change in the VBUS pin.
(8)
The RESM interrupt is generated when the device state is the suspended state, and the USB bus
state has changed (from J-state to K-state, or from J-state to SE0). Recovery from the suspended
state is detected by means of the resume interrupt.
(9)
The BCHG interrupt is generated when the USB bus state has changed. The BCHG interrupt can
be used to detect whether or not the function device is connected when the host controller function
has been selected and can also be used to detect a remote wakeup. The BCHG interrupt is
generated regardless of whether the host controller function or function controller function has
been selected.
(10) DTCH Interrupt
The DTCH interrupt is generated if disconnection of the device is detected during full-speed
operation when the host controller function has been selected. Note that the DTCH interrupt
cannot be used in high-speed mode. Clear DTCHE to 0 in high-speed mode. To detect
disconnection during high-speed operation, additional processing is necessary, such as performing
periodic control transfers of standard requests and determining disconnection if no response is
returned from the peripheral side.
Detachment in the suspended state can be detected using the BCHG interrupt.
(11) SACK Interrupt
The SACK interrupt is generated when an ACK response for the transmitted setup packet has been
received from the peripheral side with the host controller function selected. The SACK interrupt
can be used to confirm that the setup transaction has been completed successfully.
