To those in the know:
I am after designing a Real-Time Clock circuit with 8 Data output lines,
such that at a specific time of the day it should output a set pattern of
data on its output, hold this data at the outputs for exactly 3 hours, then
revert to default (defined) for the rest of the day. Further, this change
should only happen during weekdays and not weekends or public holidays. I am
hoping to achieve this by using a RTC chip.  I am presently looking at a
chip which I believe may be able to do this (RTC-62421). Has anyone used
this chip before or have any information like datasheet, specs etc...? Any
ideas or suggestions appreciated - Tks/Darrin
