The EEPROM data memory is readable and writable
during normal operation (full V
is not directly mapped in the register file space.
Instead, it is indirectly addressed through the Special
Function Registers. There are four SFRs used to read
and write this memory:
• EECON1
• EECON2 (not a physically implemented register)
• EEDAT
• EEADR
EEDAT holds the 8-bit data for read/write, and EEADR
holds the address of the EEPROM location being
accessed. The PIC16F785/HV785 has 256 bytes of
data EEPROM with an address range from 0h to FFh.

The EEPROM data memory allows byte read and write.
A byte write automatically erases the location and
writes the new data (erase before write). The EEPROM
data memory is rated for high erase/write cycles. The
write time is controlled by an on-chip timer. The write
time will vary with voltage and temperature, as well as
from chip-to-chip. Please refer to AC Specifications in
Section 19.0 “Electrical Specifications” for exact
limits.
When the data memory is code-protected, the CPU
may continue to read and write the data EEPROM
memory. The device programmer can no longer access
the data EEPROM data and will read zeroes.
