Since hardware revision 1.11.0, the following interrupt status
registers are now W1C (i.e., write 1 clear):
1. Interrupt Source Group 0 Register (0x144) (EP0 Abort: BIT5)
2. Interrupt Source Group 2 Register (0x14C) (All bits)
And before revision 1.11.0, these registers are all R/W.
Which means software must write a 0 to clear the status.
