18.5
The USB module’s slave CPU interrupts are USBIA, USBIB, UABIC, and USBID interrupts.
Tables 18.8 and 18.9 show interrupt sources and their priorities. Interrupt sources are interrupt
flags of USBIRF0, USBIFR1, TSFR0, TFFR0, and UDTRFR. Each interrupt can be enabled or
disabled according to each interrupt enable bit of USBIER0 and USBIER1. Before initiating the
USBID interrupt process routine, the interrupt source must be determined by reading USBIRF0,
USBIFR1, TSFR0, TFFR0, and UDTRFR.
The USBIA, USBIB, UABIC, and USBID interrupts can be used as DTC activation interrupt
sources.
