Eeprom

Hi all,

I'm doing the clock using TMR0 using PIC16F84A.

Prescaler = 256
Ticks = 16 ticks per second


Seem the eeprom is non-volatile memory, the data will remain intact even power is power off.

Question:
How could I going to apply this method to my clock? Because every time I power off, the clock will automatic reset everyting.

Please give advice.
Thanks

One of three choices:

1. Don't ever power off.
or
2. Use a battery and never remove it.
or
3. Don't use TMR module of the PIC, use a RTC chip with a battery.
