Date and Time Functions available on all products
The ARMmite, ARMweb, DINkit and SuperPRO have a provision to add a battery to keep these time functions running when power is removed. That battery (ML2020) has to be installed by the user or can be special ordered for larger volume customers.
The BASICchip does not have RTC hardware. The PROplus board does not
have the RTC crystal installed.
