9.0
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. PIC16F636/639 has 256 bytes of data
EEPROM and the PIC12F635 has 64 bytes.

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 A/C specifications in
Section 15.0 “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.
Additional information on the data EEPROM is
available in the “PICmicro
Reference Manual” (DS33023).
