The banking is in external RAM.
We have sufficient code space as the microcontroller is capable of
addressing 16MB of it - (Harvard architecture so separate address and
It's main limitation is on data space, since it can only address 64KB of
ram for which 32KB is on chip for application variable storage, 16KB is
used for constant data access and the remaining 16KB would be for page
access to the external 1MB of data ram that would only be used to hold
the Lua scripts.
