Interrupt Mask Queue i Register (ETHERNETn_int_mask_qi) (i=1 to
3)
The Interrupt Mask Queue i register is a read only register indicating which interrupts are masked. All bits
are set at reset and can be reset individually by writing to the Interrupt Enable Queue i register or set
individually by writing to the Interrupt Disable Queue i register. Having separate address locations for
enable and disable saves the need for performing a read modify write when updating the Interrupt Mask
Queue i register. For test purposes there is a write-only function to this register that allows the bits in the
Interrupt Status Queue i register to be set or cleared, regardless of the state of the mask register
