4. After jumping to the address fetched from the exception handling vector table, program
The FPU exception flag field (Flag) of FPSCR is always updated regardless of whether or not an
FPU exception handling has been accepted, and remains set until explicitly cleared by the user
through an instruction. The FPU exception source field (Cause) of FPSCR changes each time a
floating point operation instruction is executed.
When the V bit in the FPU exception enable field (Enable) of FPSCR is set and the QIS bit in
FPSCR is also set, FPU exception handling is generated when qNAN or ±∞ is input to a floating
point operation instruction source.
5.8
When an address error, bus error, FPU exception, register bank error (overflow), or interrupt is
generated immediately after a delayed branch instruction, it is sometimes not accepted
immediately but stored instead, as shown in table 5.11. When this happens, it will be accepted
when an instruction that can accept the exception is decoded.
