* [SCLD][super::scld] (Timex) modes are also supported: secondary screen, hi-color, hi-res, and shadow screen bank.
* Port `0xFF` has priority over the register port. Bits 0 to 5 written to port `0xBF3B` with mode group set
are bitwise ORed with the bits written previously to port `0xFF`. When in palette mode, bits are not modified.
* Reading of the value previously written to port previously written to port `0xFF` is disabled by default,
to not confuse some programs (BBC BASIC), that the chipset supports SCLD MMU paging. This can be enabled
with [UlaPlus::enable_reading_scld_mode].

* The ULAplus capabilities can be disabled or enabled in run time with [UlaPlus::enable_ulaplus_modes].
* Hard reset sets the screen and color mode to the default and sets all palette entries to 0, but doesn't change
the ULAplus capabilities disable flag.
