possible interrupt addresses to single-step such instructions. If this is unacceptable, other debug features
can be used. Refer to
Exception register settings.
Execution resumes at offset 0x0D00 from the base address indicated by MSR[IP].
3.15.4.12 Floating-Point Assist Exception (0x0E00)
A floating point assist exception occurs when the following conditions are true:
These conditions are summarized in the following equation:
Note that when ((MSR[FE0] | MSR[FE1]) AND FPSCR[FEX]) is set as a result of move to FPSCR, move
to MSR or rfi, a program exception is generated, rather than a floating-point assist exception.
A floating point assist exception also occurs when a tiny result is detected and the floating point underflow
exception is disabled (FPSCR[UE] = 0).
The register settings for floating-point assist exceptions are shown in

If the exception occurs during an instruction fetch in Decompression On mode, the SRR0 register will contain a
compressed address.
Machine State Register (MSR)
A floating-point enabled exception condition is detected;
The corresponding floating-point enable bit in the FPSCR (floating point status and control
register) is set (exception enabled); and
MSR[FE0] | MSR[FE1] = 1
(MSR[FE0] | MSR[FE1]) AND FPSCR[FEX] = 1
