Notes

white background: duplicates/useless but valid

Addressing Modes:

R,n7/I: R, [-64..63] with or without indirection
R,n6: (X|Y|S|PC), [0 .. 63]
R,n13/I: (X|Y|S|PC), [-4096 .. 4095] with or without indirection
i8+: 16 bit constant encoded in 8 bits, possible values: [-64 .. 127] and [0 .. 63] * 1024
ir = inter register:
- r1 and r2 can be one of:
- 8-bit registers: a, b, cc, 0x00, ddr, odr, idr, 0xff
- 16-bit registers: x, y, s, pc, u, d (d = a register as hi byte and b register as lo byte)
- Unless only 8 bit registers are used the computation is always done in 16bit (incl. status regs), 8 bit registers are sign extended
idx:
- (X|Y|S|PC|U), (a|b)
- (X|Y|S|PC|U) + (a|b)
- [ (X|Y|S|PC|U), (a|b) ]
- [ (X|Y|S|PC|U) + (a|b) ]
- (X|Y|S|PC|U)+
- (X|Y|S|PC|U)++
- -(X|Y|S|PC|U)
- --(X|Y|S|PC|U)
- [ (X|Y|S|PC|U)++ ]
- [ --(X|Y|S|PC|U) ]
- (X|Y|S|PC|U), [0..7]
- [ (X|Y|S|PC|U), [0..7]*2 ]

Operands:

bsru: branch sub routine, store return pc into u (instead of the stack as with bsr)
retu: copy u into pc to return from subroutine, aka leapc u,0
eab: exchange registers a and b
ect: exchange flags c and t

Alias:

negR = rsbr R, 0x00 (a and b can also use rsba 0x00 / rsbb 0x00)
comR = rsbr R, 0xff (a and b can also use rsba 0xff / rsbb 0xff or eorai 0xff / eorbi 0xff)
incR = subr R, 0xff (a, b, x and y have dedicated ops)
decR = addr R, 0xff (a, b, x and y have dedicated ops)
tstR = andr R, R (a and b have dedicated ops)
clrR = eorr R, R (a and b have dedicated ops)
lslR = addr R, R (a and b have dedicated ops)
rolR = adcr R, R (a and b have dedicated ops)
reti = pulls cc,pc

Flags:

c, v, z, n, i, s, t, 0 (0 always reads 0, this is how bra/brn works implicitly)
ops that set NVZSC: add, adc, cmp, cpc, lsl, lsr, rol, ror, rsb, rsc, sub, sbc
ops that set NVZS: dec, inc
ops that set NVZS: and, bit, clr, eor, ld, or, tst (exception: the ***cci ops) (V is 0)
ops that set Z: leax, laey, laeu
special: andcci, bitcci, eorcci, ect, orcci, pull, reset, swi, wai
ops that set none: br, eab, jsr, jsru, leas, leapc, nop, push, ret, retu, st, swi2
adc, cpc, sbc and rsc do set the Z only if the result is zero and the previous result was also zero
