23.5.8
Together with USB interrupt flag register 0, USBIFR1 indicates interrupt status information
required by the application. When an interrupt source occurs, the corresponding bit is set to 1 and
an interrupt request is sent to the CPU according to the combination with USB interrupt enable
register 1. Clearing is performed by writing 0 to the bit to be cleared, and 1 to the other bits.
Bits 7 to 4—Reserved: These bits are always read as 0. The write value should always be 0.
Bit 3—USB Connect Status (VBUSMN): This bit is a status bit for monitoring the state of the
USBF_VBUS pin. It reflects the state of the USBF_VBUS pin.
Bit 2—EP3 Transfer Request (EP3 TR): This bit is set if there is no valid transmit data in the
FIFO buffer when an IN token for endpoint 3 is received from the host. A NACK handshake is
returned to the host until data is written to the FIFO buffer and packet transmission is enabled.
Bit 1—EP3 Transmit Complete (EP3 TS): This bit is set when data is transmitted to the host
from endpoint 3 and an ACK handshake is returned.
Bit 0—USB Bus Connect (VBUSF): This bit is set to 1 when connecting to or disconnecting
from the USB bus. The USBF_VBUS pin is used to detect connection/disconnection.
The USBF_VBUS pin must be connected, as it is needed inside the module.
