PIC16F887 and DS1307

[Melanie]

We're talking about a DS1307 RTC here (and ignoring the MSB of certain Registers) where the only valid individual digits are in the range 0-9. The subroutine converts two digit DECIMAL in the range 0-99 to a single BCD Byte. $EC is not a valid conversion requirement for this application.

My point was that there isn't any sort of error checking, flipped bits, logic errors, and so on...
