Assembly of MOVE Rx, Ry

Using version 2.35_20220830 from esp-idf 5.1, `MOVE Rx, Ry` is apparently assembled as:

```
(MSB)
1110000100000000000000000yyyyxx
```

i.e. Rsrc2 is equal to Rsrc1, as if it was `MOVE Rx, Rx, Ry`, while TRM doesn't specify Rsrc2 for MOVE instruction.
Shouldn't it be:
```
(MSB)
111000010000000000000000000yyxx
```
instead?

Is it intended behavior?
