Dual PAN is something like nice to have.
I suggest initialy to implement only PAN ID 0 support. It is easier and
you would have fewer problems with the sequence manager. If the driver
is stable and tested, then you can expand it and add support for dual PAN.

Since there are some incompletenesses in the reference manual, a good
help could be [1], also there is kw2xrf driver in RIOT-OS [2] and mcr20a
driver in zephyr-project (drivers/ieee802154/ieee802154_mcr20a*) [3].
