Underflow
trapping for IEEE 754 underflow exceptions:
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
Inexact. Set when an IEEE 754 inexact exception occurs,
regardless of whether or not software trapping for inexact
exceptions is enabled. Writing a “0” to this position clears
the status bit.
0 = No inexact exception detected
1 = Inexact exception detected
Underflow. Set when an IEEE 754 underflow exception
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
Overflow. Set when an IEEE 754 overflow exception
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
1 = Overflow exception detected
Invalid Operator. Set when an IEEE 754 invalid operator
exception occurs, regardless of whether or not software
trapping for invalid operator exceptions is enabled. Writing
a “0” to this position clears the status bit.
0 = No invalid operator exception detected
1 = Invalid operator exception detected
