36.3.2
IFR1 is an interrupt flag register for VBUS and EP3. When each flag is set to 1 and an interrupt is
enabled in the corresponding bit of IER1, an interrupt request (USBFI0 or USBFI1) specified by
the corresponding bit in ISR1 is issued to INTC.
Clearing the flag is performed by writing 0. Writing 1 is not valid and nothing is changed. To clear
bits, access the register so that 0 should be written only to the bits for the interrupt sources to be
cleared and that 1 should be written to the other bits. Do not use a bit field declaration of the C
language to clear bits.
