Question on BTST (and BCLR, BCHG, BSET)

[xahon]

Why BTST dest size is 2 bytes?

m68kdecode/imask.txt

Line 20 in 2c49682

BTST 0000_ddd1_00mm_mrrr sz=4; src=cs.data_reg_op(d); dst=cs.ea(r, m, 2);

According to the manual it can't have Word type, only Byte and Long.

I also noticed that you set mask for the next word as follows

m68kdecode/imask.txt

Line 25 in 2c49682

BTST 0000_1000_00mm_mrrr 0000_000n_nnnn_nnnn sz=1; src=IMM16(n); dst=cs.ea(r, m, 1);

But the manual says it's 8-bits value

Is it a bug or you made it intentionally for some reason? The same applies to the next 3 instructions

---

An offtop question:
Can you explain how does these 4 instructions work?
I mean that what is "bit number" in the data/register? Both data and register can contain not a single but multiple bits (up to 32 in a register and 8 in next word data [according to the manual scheme]) like 0b01010101. It doesn't make sense then because the product of the instruction is a single bit in CCR

Probably a copy-pasta oversight. I'm not using this library for anything currently.
