Assembly of MOVE Rx, Ry

[pguyot]

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?
