Interrupt Request Configuration Address Register (INT_CFADDR)

Interrupt Request Configuration Data Register Select Bits — These bits determine which of the 128
configuration data registers are accessible in the 8 register window at INT_CFDATA0–7. The hexadecimal
value written to this register corresponds to the upper nibble of the lower byte of the interrupt vector, i.e.,
writing 0xE0 to this register selects the configuration data register block for the 8 interrupt vector requests
starting with vector (vector base + 0x00E0) to be accessible as INT_CFDATA0–7.
Note: Writing all 0s selects non-existing configuration registers. In this case write accesses to
Figure 16-5. Interrupt Configuration Address Register (INT_CFADDR)
= Unimplemented or Reserved
INT_CFDATA0–7 will be ignored and read accesses will return all 0.
