63F09 — 2024-05-28T12:25:30Z
Warning: in 63F09 mode (32 bits), there is no 0 or Z (zero) register. Nevertheless, in 6309 mode (16 bits), Z is usable with EXG and TFR opcodes.
In 63F09 mode, EXG and TFR operands are modified to exchange or transfer new Q and DS registers.

FPUCC contains three bits for rounding mode and five bits for status. It cannot be direcly addressed.

RND2	RND1	RND0	NV	DZ	OF	UF	NX
RND2, RND1, RND0 are set by SETRNE, SETRTZ, SETRDN, SETRUP, SETRMM or SETDYN instruction.
other bits are used as flags set by FPU:
- NV : invalid result
- DZ : division by zero
- OF : overflow
- UF : underflow
- NX : inexact
These flags can be tested by (L)BNV, (L)BDZ, (L)BOV, (L)BUN and (L)BIX instructions. Two other branch instructions (L)BFT and (L)BFF are used to test boolean result of FPU operation (for example FCMPS).
[1] EIRQ (extended interrupt request): 24 new hardware interrupt requests available in 63F09 mode.
