Hola:
Pues solo mira la ayuda y tienes todo solucionado:
para leer:
READ Address,Var
Read the on-chip EEPROM at the specified Address and stores the result in Var. This instruction may only be used with a PICmicro that has an on-chip EEPROM data area such as the PIC16F84, PIC16C84 and the PIC16F87x series. READ will not work on devices with on-chip I2C interfaced serial EEPROM like the 12CE67x and 16CE62x parts. Use the I2CREAD instruction instead.
Example
READ 5,B2 ' Put the value at EEPROM location 5 into B2
Para Escribir:
WRITE Address,Value
Write Value to the on-chip EEPROM at the specified Address. This instruction may only be used with a PICmicro that has an on-chip EEPROM data area such as the PIC16F84, PIC16C84 and the PIC16F87x series. WRITE is used to set the values of the on-chip EEPROM at runtime. To set the values of the on-chip EEPROM at programming-time, use the DATA or EEPROM statement. Each WRITE is self-timed and takes about 10 milliseconds to execute on a PICmicro.
If interrupts are used in a program, they must be turned off (masked, not DISABLEd) before executing a WRITE, and turned back on (if desired) after the write instruction is complete. An interrupt occurring during a WRITE may cause it to fail. WRITE will not work on devices with on-chip I2C interfaced serial EEPROM like the 12CE67x and 16CE62x parts. Use the I2CWRITE instruction instead.
Example
WRITE 5,B0 ' Send value in B0 to EEPROM location 5
