Section 25 USB Function Controller (USBF)
25.3.2
IFR1 is an interrupt flag register for VBUS and EP3. When each flag is set to 1 and the interrupt is
enabled in the corresponding bit of IER1, an interrupt request is generated as specified by the
corresponding bit in ISR1. Clearing is performed by writing 0 to the bit to be cleared. Writing 1 is
not valid and nothing is changed.

[Setting condition]
When data to be transmitted to the host is written to
EP0i, then data is normally transferred from the
function to the host, and an ACK handshake is
returned.

These bits are always read as 0. The write value
should always be 0.
USB Connection Status
Status bit to monitor the USBF_VBUS pin state.
Reflects the state of the USBF_VBUS pin.
0: Disconnected
1: Connected
[Setting condition]
When an IN token is issued from the host to EP3 and
the FIFO buffer is empty.
