I'm designing a PIC clock circuit using the ST I2C interfaced RTC part
MT41T81, and have found the datasheet a bit brief.  I've had no luck
finding example code, which would make things a lot easier from a
newcomer perspective.  I want to code a PIC read/write of the RTC
registers in Microchip C18, and any example code in this language
would be really useful, though I would find an assembler listing for
the task useful background.  Any pointers to some example code would
be really welcome, thanks for any help with this,
