pioasm: python output for RP2350 mov pindirs incorrect

[magy00]

word() is prepended with part of the mov() that it replaces:

$ cat test.pio
.program test
.pio_version 1
_:  mov pindirs, null
jmp _

$ pioasm -o python test.pio

import rp2
from machine import Pin
# ---- #
# test #
# ---- #

@rp2.asm_pio()
def test():
    wrap_target()
    label("0")
    mov(, null)             word(41059)                           # 0
    jmp("0")                              # 1
    wrap()

Ideally, this could look something like:

import rp2
from machine import Pin
# ---- #
# test #
# ---- #

@rp2.asm_pio()
def test():
    wrap_target()
    label(0)
    word(0xa063)  # mov(pindirs, null)  # 0
    jmp(0)                              # 1
    wrap()

ping @dpgeorge Just out of curiosity, does the PIO support in MicroPython include the new instructions / options added for RP2350? (which I guess would be "nicer" than just emitting word() functions?)

There's a thread in the forum with some hacks to add some of the features:

No, we don't support the new RP2350 PIO options yet.
