Matching time conditions

[malc-c]

Malcolm, you can't have '&$03' for MINUTES (the way you have for HOURS)... but can you figure why and what value it should be if not $03? Correct that small omission and your code will run (there's incentive for you).

I have a hunch it's to do with the register map



Only the 1st 4 bits are used for hours (0-23) when in 24 Hr mode, where as the minutes use 7 bits of the byte, the latter 3 to store the tens. However I confess at the moment I'm at a loss as to what value I need
