331 The flag field contains one of the following:
333 - Flag unaffected
334 * Flag affected
335 0 Flag reset
336 1 Flag set
337 ? Unknown
338 P Parity-Flag used as Parity
339 V Parity-Flag used as Overflow-flag
342 r means register. Can be B,C,D,E,H,L or A.
343 Add this to last byte of OP-code:
344 Reg regbits
345 B 0
346 C 1
347 D 2
348 E 3
349 H 4
350 L 5
351 A 7
353 On >LD (IX+n),r< and >LD (IY+n),r< you
354 add it to the byte before the last.
357 b means bit. Can be 0-7. Increase the
358 last byte of OP-code with 8*b.
359 Used in SET, BIT and RES.
362 If there is two numbers given at Clock,
363 then the highest is when the jump is
364 taken.
