DTLB Modified Exception
Floating-point Exception
Coprocessor Exception
The DTLB Modified exception is generated when a data memory write hits a valid TLB entry, but
the Dirty bit of the entry is 0. This indicates that the page is not writable.
The Floating-point exception is generated when the optional Floating-Point Hardware signals
that an IEEE exception occurred, or when another type of error from the floating-point hardware
occurred..
The Coprocessor exception occurs when the addressed coprocessor does not acknowledge an
instruction. This permits software implementation of coprocessors.
