13.3.6 Read Interrupt register (R: C0H)
This command indicates the sources of interrupts as stored in the 4-byte DcInterrupt
register. Each individual endpoint has its own interrupt bit. The bit allocation of the
DcInterrupt register is shown in Table 108. Bit BUSTATUS is used to verify the current
bus status in the interrupt service routine. Interrupts are enabled via the
DcInterruptEnable register, see Section 13.1.5.
Remark: While reading the DcInterrupt register, read both 2 bytes.
Code (Hex): C0 — read interrupt register
Transaction — read 2 words
Remark: For details on interrupt control, see Section 8.6.3.
