36.3.3
IFR2 is an interrupt flag register for SURSS, SURSF, CFDN, SOF SETC, and SETI. When each
flag is set to 1 and an interrupt is enabled in the corresponding bit of IER2, an interrupt request
(USBFI0 or USBFI1) specified by the corresponding bit in ISR2 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.
