'CLOCK-CALENDAR ... PCF8583 ... PIC CODE ?'
Someone can help me to find an ASM code for PIC ( 16C84 in better ) to
realize, like an hobbiest, a simple and normal CLOCK ?
Thanks in advance.

If you are just trying to implement a clock (no calendar) and that is all
your system is going to do... skip the RTC (Real Time Clock) IC and refer to
Microchip Application Note AN590 (see http://www.microchip.com) which implements a
clock in a 16c54. Although I haven't looked at the code, I can see no good
reason why it shouldn't work in an '84 with minor modification. The only
exception is that you have less I/O so you will have to get fancy with the
switch inputs, multiplexing I/O in some way. Refer to AN529 'Multiplexing
LED Drive and a 4*4 Keypad Sampling' for some hints.

Luckily Microchip have done this for you - look in the application notes
at their web site
