20.9.6.1.3 Interrupt Register for Endpoint 0 Plus Transmit Endpoints 1 to 15 (USBn_INTRTX)
The interrupt register for endpoint 0 plus transmit endpoints 1 to 15 (USBn_INTRTX) is a 16-bit
read-only register that indicates which interrupts are currently active for endpoint 0 and the TX
endpoints 1–15. Note also that all active interrupts are cleared when this register is read.
The interrupt register for endpoint 0 plus transmit endpoints 1 to 15 is shown in
described in Table
