That's correct.

There is also INIR, which replaces the DEC B with a DJNZ. ALso, there is
OUTI and OTIR... They are the same exect for that they OUT instead of IN.
It's quite useful for sending or recieving multiple bytes (however; it's not
that useful on the TI... it's made for use with a bit more advanced external
devices).
