0 = Disable software trapping for underflow exceptions
1 = Enable software trapping for underflow exceptions
Overflow Trap Enable. Enables/disables software trapping
for IEEE 754 overflow exceptions:
0 = Disable software trapping for overflow exceptions
1 = Enable software trapping for overflow exceptions
Invalid Operator Trap Enable. Enables/disables software
trapping for IEEE 754 invalid operator exceptions:
0 = Disable softw are trapping for invalid operator
exceptions
1 = E nab le softw are tra ppin g for in va lid o pera tor
exceptions

occurs, regardless of whether or not software trapping for
underflow exceptions is enabled. Writing a "0" to this
position clears the status bit.
0 = No underflow exception detected
1 = Underflow exception detected

occurs, regardless of whether or not software trapping for
overflow exceptions is enabled. Writing a "0" to this
position clears the status bit.
0 = No overflow exception detected
